Detailed explanation-1: -Because all biological processes are dependent on pH, cells and organisms must maintain a specific and constant pH in order to keep their enzymes in the optimum state of protonation. This system provides the maximum buffering capacity near pH 6.86 (the pKa of H2PO4-).
Detailed explanation-2: -A buffer is a chemical agent that helps keep the pH of a solution approximately constant, even when acids or bases are added. Buffering is vital in living systems because it allows them to maintain homeostasis, or a relatively consistent internal environment.
Detailed explanation-3: -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.
