Why does metabolic waste be removed from the body?

Answer 1

Metabolic wastes, particularly nitrogenous wastes that are the by-products of the breakdown of proteins and nucleic acids, are toxic to cells and must therefore be removed quickly. Nitrogenous wastes have the ability to change the ph of cells and interfere with membrane transport functions and also may denature enzymes. :)

Answer 2

the removal of co2 is important for cell functioning because it lowers the pH of solution in which it is dissolved therefore affecting enzyme functioning and possible the shape of hemoglobin molecules.this causes decrease in oxygen saturation.both of are undesirable conditions thus necessary for the removal of co2/metabolic waste from living cells to ensure correct cellular process

metabolic waste is toxic to cell and its function

Answer 3

Do you realize how big your body would be if you do not empty your body waste. Also, the body would release poison to kill you if you do not remove body waste. Would you really want to keep body waste inside of you?

Answer 4

Waste products are substance not needed by the body or in excess in the body. If these were not removed, some are toxic and would eventually poison the body (e.g. hydrogen peroxide). Others, would disturb the balance (homeostasis) that the body requires to function properly (e.g. if carbon dioxide were not expelled, it would decrease the pH/increase the acidity of the blood in the body).

Answer 5

Because it is impossible to store them.

Yes, but why? Metabolic wastes can't be stored, true, but the reason is that they are poisonous to the cell and eventually to the entire body if they are not metabolized and excreted. For example, nitrogenous wastes (urea) are filtered out by the kidneys. If someone is on dialysis, he can only go 3 days without having his blood artificially filtered because the buildup of urea (uric acids) will soon poison the entire body.

Carbon dioxide must be exhaled from the lungs, because a buildup of CO2 in the blood would block the ability of the blood to carry enough oxygen to the cells, and the cells would begin to die.

Our livers also metabolize many substances, including alcohol, which would be toxic to the body if allowed to build up in the cells. Alcohol is so toxic that the liver can become hard and begin to lose its function (cirrhosis) if a person is an alcoholic and puts too much alcohol into the blood on a regular basis for the liver to metabolize properly.

There is more, but I think you get the idea. Metabolic wastes means just that; these are toxic byproducts of cellular respiration and other metabolic processes within the cells, and they must be excreted in one way or another so that the cells of the body remain healthy, functional and are not poisoned by buildup of these waste products.

Answer 6

That is intelligent question! The cell metabolites are carbon bi oxide and nitrogenous waste products. The carbon bi oxide reduce the pH of the blood. Your body pH has to be maintained in very narrow range. Why this is so is not clear to me. But low pH is very powerful stimulant for the respiration. It is relatively very easy to clear the extra carbon bi oxide. The nitrogenous waste products are very toxic to the brain. Body spends lot of blood supply and energy to remove the nitrogenous waste products.

Answer 7

becoz they maintain the whole system of body

Answer 8

Generally speaking, the waste gets in the way of important reactions (that's why the waste has to be removed).
