Which of the Following is Least Associated with Monoamine Oxidase

Question

Which of the following is least associated with monoamine oxidase (MAO)?
A) Enzyme that degrades norepinephrine
B) Found within all cholinergic nerve terminals
C) Associated with sympathetic activity
D) Associated with adrenergic fibers

Accepted Answer

MAO is not found within cholinergic nerve terminals, which release acetylcholine as their neurotransmitter. MAO is primarily associated with the degradation of monoamine neurotransmitters such as norepinephrine, dopamine, and serotonin, and is involved in regulating sympathetic activity and adrenergic fibers.
