Select the correct statement about renal mechanisms of acid- base balance.
A)The kidneys are the most important mechanism for eliminating all bicarbonate ions.
B)The kidneys are not able to excrete phosphoric acid.
C)Excreted hydrogen ions are unbound in the filtrate.
D)Kidney tubule cells are able to synthesize bicarbonate ion.

Question

Quizplus · Accepted Answer

Kidney tubule cells possess an enzyme called carbonic anhydrase which enables them to synthesize bicarbonate ions from carbon dioxide and water. The kidneys are also able to excrete phosphoric acid. Excreted hydrogen ions are typically buffered by filtered bicarbonate ions or combined with phosphate or ammonia to form buffered ions in the filtrate.
