During acidosis, ammonia plays a key role in allowing for continued renal H⁺ secretion.

Question

Quizplus · Accepted Answer

During acidosis, ammonium ions (NH4+) are produced in the liver from the deamination of amino acids and then transported to the kidneys. In the kidneys, they are exchanged for sodium ions (Na+) in the proximal tubules, leading to continued secretion of hydrogen ions (H+) and reabsorption of bicarbonate ions (HCO3-) in the distal tubules, helping to regulate pH balance in the body.
