H⁺ secretion is coupled to bicarbonate reabsorption.

Question

Quizplus · Accepted Answer

H⁺ is a type of proton pump found in the intercalated cells of the collecting ducts in the kidney. This proton pump is responsible for secreting hydrogen ions into the urine, which helps to regulate the acid-base balance of the body. Bicarbonate ions are reabsorbed by the proximal tubules of the kidney, and the secretion of hydrogen ions by the intercalated cells is coupled to the reabsorption of bicarbonate ions. This process helps to maintain a constant pH level in the blood.
