Question

Chemical responsible for increase in blood pressure due to renin action is

• A. Aldosterone
• B. Angiotensinogen
• C. Angiotensin I
• D. Angiotensin II

Answer 1

The correct option is D Angiotensin II

Angiotensin II raises blood pressure (BP) by a number of actions, the most important ones being vasoconstriction, sympathetic nervous stimulation, increased aldosterone biosynthesis and renal actions. The liver creates and releases a protein called angiotensinogen. This is then broken up by renin, an enzyme produced in the kidney, to form angiotensin I. Angiotensin I is converted to angiotensin II by the enzyme angiotensin-converting enzyme (ACE).
