Angiotensin Converting Enzyme

Question

Angiotensin converting enzyme A) Cleaves angiotensinogen to angiotensin I B) Cleaves angiotensin I to angiotensin II C) Release aldosterone D) Causes vasoconstriction E) Retains Na⁺

Accepted Answer

Angiotensin-converting enzyme (ACE) specifically cleaves angiotensin I to angiotensin II, which is a potent vasoconstrictor and stimulates aldosterone release, but the enzyme itself does not directly release aldosterone or cause vasoconstriction, nor does it directly retain sodium.
