The angiotensin-converting enzyme (ACE) converts angiotensin I almost instantly to which substance? ...

Correct Answer: 1
Rationale 1: ACE converts angiotensin I to angiotensin II. This happens almost immediately because ACE lies on the membranes of the blood vessels.
Rationale 2: ACE does not convert angiotensin I to aldosterone.
Rationale 3: ACE does not convert angiotensin I to angiotensinogen.
Rationale 4: ACE does not convert angiotensin I to renin.
Global Rationale: ACE converts angiotensin I to angiotensin II. This happens almost immediately because ACE lies on the membranes of the blood vessels. ACE does not convert angiotensin I to aldosterone, angiotensinogen, or renin.
