A) lysosomes of sympathetic preganglionic neurons
B) smooth ER of parasympathetic postganglionic neurons
C) Golgi apparatus of parasympathetic postganglionic neurons

Question

Quizplus · Accepted Answer

Monoamine oxidase is an enzyme located in the mitochondria, and it is involved in the breakdown of monoamines, which are neurotransmitters. This process is significant in the neurons of the sympathetic nervous system, particularly in the postganglionic neurons, where neurotransmitters like norepinephrine are broken down.
