By What Mechanism Do Acid/base Buffer Systems Minimize PH Changes

Question

By what mechanism do acid/base buffer systems minimize pH changes?
A) By converting weak bases to strong bases
B) By converting strong acids to weak acids
C) By increasing the respiratory rate
D) By promoting the renal excretion of hydrogen ions

Accepted Answer

Buffers work by converting strong acids to weak acids or strong bases to weak bases, thereby minimizing changes in pH. However, the specific mechanisms involving respiratory rate or renal excretion are not direct actions of buffer systems but rather physiological responses to maintain pH balance.
