How do buffers minimize change in the pH of biological systems?

Question

Quizplus · Accepted Answer

Buffers can both absorb and donate protons (H+) to maintain a constant pH in biological systems. When there is an excess of H+ ions, the buffer will absorb them, and when there is a shortage of H+ ions, the buffer will donate them. The ability of buffers to act as both a weak acid and a weak base allows them to resist changes in pH, making them important for maintaining the pH of biological systems.
