Question 5 of 5

Which of the following mechanisms operates in the nephron to maintain pH balance in the body?

A. Bicarbonate ions from the tubule cells are secreted into the filtrate, then H+ + HCO3- â†’ H2CO3 â†’ CO2 + H2O B. In tubule cells CO2 + H2O â†’ H2CO3 â†’ H+ + HCO3- then hydrogen ions are secreted into the filtrate C. In tubule cells CO2 + H2O â†’ H2CO3 â†’ H+ + HCO3- then hydrogen ions are transported into the peritubular capillaries D. In tubule cells CO2 + H2O â†’ H2CO3 â†’ H+ + HCO3- then bicarbonate ions are secreted into the filtrate

Correct Answer: B

Rationale: Hydrogen secretion and bicarbonate reabsorption regulate pH.
