KROK 1 2021 – Question 75 · KROK (Medicine) · Biological Chemistry
During mental stress, a hormone-sensitive enzyme triacylglycerol lipase activates in fatty tissues. What secondary messenger takes part in activation of this enzyme?
- A. Cyclic guanosine monophosphate
- B. Inositol triphosphate
- C. Ca²⁺
- D. Diacylglycerol
- E. Cyclic adenosine monophosphate
Hint
Lipolysis in fat cells is switched on by catecholamines through a G-protein-coupled receptor and a protein kinase; decide which listed second messenger belongs to that cascade rather than to phospholipase C or guanylate cyclase.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
