Why do cells need a buffer system?
|
|
Chemical processes in the cell are sensitive to the concentration of H+ and OH-
|
|
|
Cells do not have a buffer system
|
|
|
Cells need acids and bases to survive
|
|
|
The pH range of cells can withstand large changes
|
Explanation:
Detailed explanation-1: -Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ ions or OH–ions, thereby maintaining an overall steady pH in the solution.
Detailed explanation-2: -A variety of buffering systems permits blood and other bodily fluids to maintain a narrow pH range, even in the face of perturbations. A buffer is a chemical system that prevents a radical change in fluid pH by dampening the change in hydrogen ion concentrations in the case of excess acid or base.
