What is the role of buffers in a cell?

Answer 1

Buffers act in biological systems by keeping pH in a certain range with little or no change as part of the homeostatic regulatory actions of the body. Keeping pH within a certain range is important for things like chemical gradients, enzyme function, and preventing damage to the cells and proteins. A good example buffer system is the blood bicarbonate (HCO3+) buffer system. The body converts most CO2 into carbonic acid (H2C03) which dissolves to form bicarb and H+ ions, creating a buffer system that can react quickly to changes in blood pH.

Answer 2

A buffer is an aqueous solution which resists change in pH.

Buffers are usually of three types:

1. Acidic buffers: They consist of a weak acid and its salt of a strong base. They keep the pH constant in the acidic range.
2. Basic buffers: They consist of a weak base and its salt of a strong acid. They keep the pH constant in the alkaline range.
3. Single salt buffer: They consist of a salt of a weak acid and weak base and maintian the pH constant at 7,i.e., the neutral pH.

In organisms, metabolic reactions are usually pH-specific. The reactions function best at the optimum pH. If there is any change in the pH, the reaction can slow down. Hence, in biological systems, buffers play a pivotal role in maintaining functionality of reactions.

Answer 3

A buffer is solution used to maintain the PH of the solution or system constant. because many reactions taking place inside the cell required an optimum temperature for the action of enzymes . so buffer provides that optimum temperature to that enzyme to perform its action.

Answer 4

Changing the pH will change the properties of many important biological molecules - including amino acids (proteins).

Buffers are vital because maintain a stable pH - and therefore the properties of reactants involved in important cell processes will remain the same - allowing the functions to be carried out.

Answer 5

Buffers in a cell help maintain the pH within a specific range by accepting or donating protons (H+ ions) to prevent drastic changes in acidity or alkalinity. This is crucial for maintaining the proper functioning of enzymes and other cellular processes that are sensitive to changes in pH. Buffers also aid in stabilizing the internal environment of the cell.

Answer 6

Just because mikenna says and what mikenna says goes!!

Answer 7

Cells require a certain pH range to function. With out buffers, the pH can become unsuitable for the cell to continue to live.
