Which of the following enzymes is important for the metabolism of catecholamines?
A)Tyrosine hydroxylase
B)Acetylcholinesterase
C)Superoxide dismutase
D)Hydrocortinase
E)Adenyl cyclase

Question

Quizplus · Accepted Answer

Tyrosine hydroxylase is the enzyme necessary for the metabolism of catecholamines, as it converts the precursor tyrosine into L-dopa, which is then converted into dopamine, norepinephrine, and epinephrine. Acetylcholinesterase is important for the metabolism of acetylcholine, not catecholamines. Superoxide dismutase is an enzyme that helps to protect cells against oxidative stress. Hydrocortinase is not a known enzyme. Adenyl cyclase catalyzes the formation of cyclic AMP from ATP, which is important for many cellular signaling processes, but not specifically for the metabolism of catecholamines.
