Under Which Condition Will the Renal Reabsorption of Bicarbonate Increase

Question

Under which condition will the renal reabsorption of bicarbonate increase?
A) As a compensatory mechanism for respiratory acidosis
B) Whenever blood pH exceeds 7.45
C) As a compensatory mechanism for metabolic alkalosis
D) Whenever a person hyperventilates

Accepted Answer

Renal reabsorption of bicarbonate increases as a compensatory mechanism for respiratory acidosis. This is because the kidneys attempt to retain more bicarbonate to neutralize the excess acid in the blood, helping to restore the blood pH to normal levels.
