Which of the following is correct regarding the renin‐angiotensinogen mechanism?

A. A decrease in blood pressure results in the release of renin which converts angiotensinogen I to angiotensinogen II. The angiotensin‐converting enzyme converts angiotensinogen II to angiotensin, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.

B. A decrease in blood pressure results in the release of renin which converts angiotensinogen to angiotensin I. The angiotensin‐converting enzyme converts angiotensin I to angiotensin II, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.

C. A decrease in blood pressure results in the release of angiotensin‐converting enzyme, which converts angiotensin to angiotensinogen I. The angiotensin‐converting enzyme then converts angiotensinogen I to angiotensinogen II. Angiotensinogen II then stimulates the adrenal cortex to secrete renin, which is involved in increasing blood pressure.


This is not a function of insulin

A. Decreasing glycogenolysis

B. Lipogenesis

C. Gluconeogenesis

D. Gycogenesis
