RBCs don't have a nucleus, performs many functions. Who else is there to look after the cell and its functional and metabolic behavior?

Thanks for A2A. Interestingly, there are approximately 2.5 million RBCs produced per second in our human body. Our RBCs after differentiating from erythroblasts in the bone marrow, are released into the main bloodstream to last for approximately 120 days. Our RBCs

What are the differences between human cells and other animals cells?

The cells have homologous similarities to its structure but each organism has it's own unique specific DNA coded information for instructions to signal the cells to form a certain type of organism. Each cell is different from organism to organism, meaning you do not have human cells in chimpanzees nor chimpanzees cells in humans. The organisms can be organized

What is produced during anaerobic respiration in humans?

Anaerobic respiration in humans may be summarised by the word equation:glucose = lactic acid + energyIn yeast anaerobic respiration may be summarised by:glucose = ethanol + carbon dioxide + energyDuring glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This is the same reaction as

What would be the cause of low TSH levels, high creative protein levels and high white blood cell count when I have no thyroid?

TSH or thyroid-stimulating hormone is produced in the pituitary, which is in the brain. It's role is to monitor the thyroid hormone level in your blood and respond accordingly. So if thyroid hormone is low, the body makes more TSH. If thyroid hormone is high, it makes less TSH. So in someone with no

Why are honeycomb cells hexagonal in shape?

Two possible explanations exist as to why honeycomb is composed of hexagons, rather than any other shape. First, the hexagonal tiling creates a partition with equal-sized cells, while minimizing the totalperimeter of the cells. Known in geometry as the honeycomb conjecture, this was given byJan Brożek and proved much later byThomas Hales. Thus, a hexagonal

Why is cell theory not a law?

Brief explanation below. ( yes the question is not about evolution - but it explains laws and theories fairly well )Evolution is Not Just a Theory: homeYou've been told that "evolution is just a theory", a guess, a hunch, and not a fact, not proven. You've been misled. Keep reading, and in less than two minutes

Animal cell differs from plant cells in possessing?

Animal cell has no cell wall and have a higher rate of metabolism. they also posses centrioles, they lack chloroplast as they are not autotrophic, they have a smaller vacoule compared to plant cell wall, the food material stored in animal vacoule is mainly fats and proteins.but in a plant cell they have a

Are cells conscious?

For the normal meaning of consciousness in psychology and neuroscience, biological cells would not be considered conscious. One could, however, expand the definition of consciousness to includes cells, at least in a metaphorical sense.In science (psychology, neuroscience, medicine), consciousness refers to the awake state as

Can heart cells regenerate?

You need to understand the term regeneration before you get answer to your question.First of all, cells don't regenerate, tissue does. Cells divide or are specialised to perform a given function. There are many cells in any given tissue, including heart. Most

Did animal cells evolve from plant cells?

Samuel,This question has already been answered but it reminded me of a similar question a student once asked me. If we are lucky enough, once in a while, we get questions that make us think about things we already ‘supposedly' know, but in a different way. AND

Does anaerobic respiration occur in plant cells when there is a lack of oxygen?

Yeah.... clearly...Anaerobic respira­tion is the exclusive mode of respiration in some parasitic worms, many prokaryotes, several unicellular eukaryotes and moulds. In micro-organisms the term fermentation is more commonly used where anaerobic respiration is known after the name of product like alco­holic fermentation, lactic acid fermentation.The mechanism

Does fasting trigger stem cell regeneration?

Prolonged fasting forces the body to use stores of glucose, fat and ketones, but also breaks down a significant portion of white blood cells.During each cycle of fasting, this depletion of white blood cells induces changes that trigger stem cell based regeneration of new immune system cells

How are brain cells able to regenerate and what is the importance of that process?

Dead Brain Cells do not Regenerate.There are 2 functional classes of cells in the brain - Neurons & Neuroglia.Neurons, by the connections they make, constitute the ‘coordination & command centre' of the body. Neuroglia cells support (physical, metabolic, electrochemical...) neurons. If the damage

How big are animal cells compared to our cells?

How to regenerate brain cells

Stem cells sound cool, since we already own them. It is not really wide-known, but we can rewire our brain in the desirable way in a process, which takes place far after childhood. The phenomen is called

How come in plant cells the vacuoles are so much bigger than those of animal cells?

Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal,

How come you can only maintain maximum grip strength for a few seconds?

Every voluntary muscle in the body is made up of different type of muscle fibers.One type of these fibers provide strength. They produce muscle contractions that are high in power. These fibers are prone to very easy fatigue.Other type

How do animal cells and human cells differ?

Each living cell in human or other animal contains the genome of the species, and the current scientific dogma is that the genome of each species has attributes unique to the species. So yes, in that way, they are different. Perhaps, sometime in the distant

Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen. Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes

How does DNA affect the behavior of a cell when the DNA is confined to the cell's nucleus?

DNA is confined to the nucleus yes and when it has to be expressed it forms messenger RNA that can come out from the nucleus into the cytoplasm and there when out it is bound by ribosomes that make a protein of it and it is this protein that has tags on it

How many cells are in the human brain?

Its interesting that in addition to the cells in our brains, that we also have ten million cells in our eyes that are involved in processing information. These cells are actually in the retina of the eye and are interacting with each other in complex ways, and this is just part of the processing involved in sight. We

If all cells arise from preexisting cells, how did the first cell come into being?

One of the most accepted versions is that life began in the oceans, a liquid medium which allowed molecules to roam and protected them from UV radiation. First was the formation of biological monomers such as simple sugars, aminoacids and nucleotides. This

If being fat is so bad then why don't we all just get our fat cells removed?

Not possible. You need fat for padding.Not possible. You'd starve to death if you missed a few meals.It's not the fat, per se, it's the eating. If you got rid of the ability to store the extra food you ate, you'd have heaven knows what circulating

If cancerous cells are injected into a healthy person, will he/she get cancer? Why or why not?

Cancer is difficult to eradicate because to your body, cancer cells

We all know cell theory is propounded by two german scientists Schleiden (1838) and Schwann(1839) and this theory is widely accepted let's check outCells are the basic fundamental unit of structure, function, and organization in all living things.New cells are formed and come from other cells. (In other words, cells produce cells.)All living

What are the functions of the nucleus in a plant cell?

Plant Cell NucleusThe nucleus is a highly specialized organelle that serves as the information and administrative center of the cell. This organelle has two major functions. It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division).

What are the three components of the cell theory?

The three tenets to the cell theory are as described below:All living organisms are composed of one or more cells. (However, this is considered a controversy because non-cellular life such as viruses are disputed as a life form.[1] See Non-cellular life.)The

What happens when an aerobic organism is placed in an anaerobic environment?

Well, if it's an "obligate aerobe" (like a human or a penguin) then it dies.Some bacteria and fungi have the ability to switch-hit between aerobic metabolism (cellular respiration) and anaerobic metabolism (fermentation). These are called "facultative aerobes" -- or "facultative anaerobes", it

What is the definition of the cell theory?

In biology, cell theory is considered to historic scientific theory. It is clinically proven and universally accepted that most of the living organisms are made of cells. Cells are considered to be the basic unit of structure in all organisations. Over a century later, many debates about cells

What is the difference between a plant and animal cell and bacteria?

It depends. All higher organisms have bacteria besides their differentiated cells... your question is probably about differentiated cells of the organism, those which allow it look and act as it does. So in a general way I'd just say that the difference is that the plant and animal cells are

What is the difference between human primary cells and other cell types?

A primary cell is one that is grown from a tissue directly and will have a limited ability to be passaged and expanded. Cells from younger sources may be passaged up to 40 times while those from older adults may not make it past 20. Each passage enables an approximate doubling of the cells in

This material is organised as DNA molecule along with proteins to form a chromosome.Functions of Nucleus:• Nucleus contains all

What is the function of the nucleus in a cell?

The nucleus controls all the vital activities of a cell, so it is considered as the Brain of the cell.It produces chromosomes during cell division. The chromosomes tranfer hereditary characters from parent cell to daughter cell.It is directly takes part in cell division and reproduction.It produces DNA & RNA. DNA is a genetic material and RNA takes part

What is the importance of cell theory in medicine?

One tenet of the cell theory is that every aspect of bodily structure and function results from the activities of its cells. Of the thousands of medical research papers published every month (probably thousands every week), a great number and perhaps the majority

What is the meaning of high white blood cell and low red blood cell in a complete blood count?

A complete blood count (CBC) is a test that measures the cells that make up your blood: red blood cells, white blood cells, and platelets. You might get a CBC as part of your yearly check-up. Your doctor might also order it to:Check for anemia or leukemiaSee if you have another health issue or

What is the structure of DNA in a triploid nucleus?

Structure of DNA is absolutely same in haploid, diploid, triploid etc etc. The difference is in the number of Chromosome. Chromosome is highly condensed form of DNA. In Haploid there is only one copy for each chromosome. In diploid two copy for each

What organisms other than plants possess a cell wall?

In short, a ton of organisms besides plants have cell walls. Cell walls are very ancient cellular structures, coming from a time when all life inhabited water and there was a crucial need for osmotic regulation.The domains Bacteria and Archaea ubiquitously have cell walls (though they differ in composition from each other, and within Bacteria cell wall structure varies,

What will happen to the cell if the nucleus is removed?

The Nucleus,in case of eukaryotes is considered to be the ‘brain of the cell'. So, if the nucleus is removed the cell will die. Not immediately, but after some time. Because, the proteins and the mRNAs present in the cytoplasm

What would be the cause of low TSH levels, high creative protein levels and high white blood cell count when I have no thyroid?

TSH or thyroid-stimulating hormone is produced in the pituitary, which is in the brain. It's role is to monitor the thyroid hormone level in your blood and respond accordingly. So if thyroid hormone is low, the body makes more TSH. If

The golgi apparatus contains vesicles and folded membranes and is involved in cellular transport. It is a packaging organelle. The golgi apparatus packages proteins into vesicles inside of the cell before sending them to their destinations. The golgi apparatus processes proteins for

What would we become if our brain cells didn't regenerate?

The human brain can lose many brain cells without noticeable loss of function. Intelligence and behavior are a function of complexity in synaptic connectivity, and as existing brain cells are lost new synaptic pathways can be formed between remaining neurons to take over their function. There is a

When someone gains muscle, do they gain more muscle cells, and if they lose muscle, do they lose muscle cells?

Muscle growth occurs whenever the rate of muscle protein synthesis is greater than the rate of muscle protein breakdown. Both, the synthesis and breakdown of proteins are controlled by complimentary cellular mechanisms. Trauma to muscles during resistance training will immediately stimulate repair of the damaged cells via the release of several hormones that act

Where does aerobic respiration occur in a cell?

A majority of the reactions occur in the mitochondria. Aerobic respiration or cell respiration in the presence of oxygen will use the processes of glycolysis. In glycolysis 2 ATP are broken down and 4 ATP are generated to produce a net gain of 2 ATP. This is happening outside the

Which chemical is produced in the muscle cells due to anaerobic respiration?

Lactate (lactic acid).This used to be blamed for muscle fatigue, but that's known now to be untrue. Nearly all medical physiology textbooks (save one that I know) have ceased listing this among causes of fatigue. The lactate is washed out of the muscle as fast as it's formed, carried

Which is the smallest cell in the human body?

I have to say that is a great question! Because cells are not always the same there are a few contenders for the smallest cell and here they are..... Sperm – this one is really tiny is on average 3um-6um but it does have a flagellum (tail) is approximately 25um. The brain cells (Granule Cell of the Cerebellum)

Who developed the cell theory?

Well.. the first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830′s.Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory.This theory is one of the

Who performs the function of a nucleus in cells which lack it?

There are two major types of cells that lack a nucleus. The first is the prokaryotic cell, and the second is the non-nucleated eukaryotic cell. Let's take these up one at a time.Prokaryotic cells sure do lack a nucleus, but they do not lack genetic material. Their nucleus varies from the conventionally well defined and bound nucleus that typically

Why can brain cells only be lost and not regenerate like liver cells?

I don't know that exactly, but I'd like to give a reasonable explanation. My major is medicine, if you'd like to know.Brain cells can regenerate, but rather rare and slow and it's nothing compared to liver cells. But WHY?

Why do brain cells stop growing after 18 years? So, do the brain cells die too?

Neurons (brain cells) die if a Strock happens. However, the brain does some neurons elimination process (Pruning) to make the brain less crowd by unnecessary neurons and to make  more space for other new neurons to grow and proliferate.. The brain completes its growth about the

Why do liver cells regenerate?

The liver is one of the organs of the human body with the highest regeneration ability. The regeneration is a sort of compensatory regeneration in which the division of differentiated cells occurs to recover the structure and function of the injured organ.In many serious medical conditions related to the liver,

Why do other cells have a nucleus?

In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-enclosed organellefound in eukaryotic cells. Eukaryotes usually have a single

Why do some cells have no nucleus?

Cells having no nucleus are prokaryotic, but being anucleate never means the cell don't have DNA, RNA, histone proteins etc,. Nucleus is just organelle with a biological boundary surrounding genetic materials in cytoplasm of a cell. Nucleolus with nuclear envelope comprises true nucleus. It is present in the eukaryotic cells. Prokaryotic cells lack membrane bound

Why is aerobic respiration important to living organisms?

Aerobic respiration is important because it is the most effective way to produce energy from organic molecules like glucose. For photosynthesis the complement to it, using water as electron donor, is the least effective. Using hydrogen sulfide is much more effective, but it is

Why is the nucleus located in the centre of animal cells?

So that genetic information can reach all organelles in the cell easily.The nucleus of animal cells contain DNA, which codes for different polypeptides (the components of proteins). This code is copied and sent to ribosomes (the polypeptide synthesising organelle in the cell) in the form of mRNA. The ribosome then synthesizes the polypeptide according to

Does it always take at least 24 hours for autophagy to begin when fasting? If I only do a 19 hour fast, will I get none of the benefits of autophagy?

Hello.Tho I'm not an expert on this subject I have read a little bit about it -there's extensive research in cellular autophagy and apoptosis (this is also a cellular mechanism for programmed cell death)- and according to my most recent readings and my own experience in fasting I would say that it will depend on your own body and

How many stages are there in mitosis? What are the major events in each stage?

Mitosis takes 60 minutes to complete all stages, there are 5 phases: prophase, metaphase, anaphase, telophasecytokinesis.A way I was always told to remember the order is by remembering the phrase Pete Met A Tiger (PMAT) with cytokinesis being the last stage.It's important to make sure that you know that during Interphase (normal cell cycle) in the S

What will be the total number of mitotic divisions in the formation of 64 daughter cells?

I am not really sure if you are refering to number of generations/cycles that it took to reach from 1 to 64 or number of cells that underwent mitotic divisions. I will give you both answers, nonetheless.So let's start with one cellTo have 2

Why do our body cells require oxygen?

Our body cells require oxygen to release energy. The oxygen that we take in during respiration is used to break down the food we eat to release energy from it. When we breathe in oxygen, it diffuses into blood from the lung alveoli. The lung alveoli have very thin walls in order to make the diffusion

Are there fat cells in the brain?

There are no fat cells (adipocytes) in your brain; those are found only in adipose tissue. Brains have a lot of fat in them for a few reasons. First, all cells have fat in them. Cell membranes are made up of

How are cancer cells formed?

That is a really, really good question. It's such a good question that the answer isn't fully known.There are some things which are known to lead to cancer development. But, it's a probability thing. Not all cells exposed to cancer causing agents will actually develop cancer. And some cells that are not exposed

How many embryonic stems cells remain in an adult body?

Theoretically, none. After the blastocyst stage of development (where the ESCs are), the cells become cells of 1 of the 3

If our cells are continually replaced with new cells, why do we age (and die)?

Aging is not that a simple phenomenon as we see itIf I could explain it in your words-When we are infants, the number of cells formed is greater than the number of cells dying per day.Around middle age the number of cells reproducing and cells dying is almost the same.And
