Buffering is used to maintain the pH of human blood in the relatively narrow 7.3 - 7.4 range.What acid/base pair serves to buffer the blood?

Question

Quizplus · Accepted Answer

The correct acid/base pair that serves to buffer the blood is carbonic acid (H2CO3) and bicarbonate (HCO3^-), which corresponds to choice C. This system works by the reversible reaction H2CO3 ↔ HCO3^- + H+, allowing the blood to resist changes in pH.
