Q: Which enzyme is released from the receptor site?
-
A
Carboxylase
-
B
Hydroxylase
-
C
Carbonic Anhydrase
-
D
Adenylate Cyclase
D
Answer:
D
Explanation:
Adenylate cyclase is an enzyme that is found in the membrane of various cells, including liver, kidney, and brain cells. It is released from the receptor site and catalyzes the conversion of ATP (adenosine triphosphate) to cAMP (cyclic adenosine monophosphate). cAMP is an important second messenger molecule that is involved in the regulation of various cellular processes, including gene expression, metabolism, and ion transport. Adenylate cyclase is regulated by a variety of signals, including G protein-coupled receptors, which activate the enzyme through a complex signaling pathway.
