Which of the following buffer systems primarily maintain intracellular pH? A)HPO₄^2-/H₂PO₄-;HCO₃-/H₂CO₃ B)H3PO₄/H₂PO₄-;histidine C)HCO₃-/H₂CO₃;H₃PO₄/H₂PO_4- D)HPO₄-/H₂PO₄-;histidine

Question

Quizplus · Accepted Answer

The buffer system that primarily maintains intracellular pH involves HPO₄- and H₂PO₄-, along with histidine. Histidine acts as a buffer when it accepts or donates protons to maintain a stable pH. Therefore, option D (HPO₄-/H₂PO₄-;histidine) is the best choice for the buffer system that primarily maintains intracellular pH.
