Answer to Question 1

C
Feedback:
The last step in the production of the neurotransmitter involves choline acetyltransferase, an enzyme that is also produced within cholinergic nerves. Just like norepinephrine, the ACh is produced in the nerve and travels to the end of the axons, where it is packaged into vesicles. Calcium is an electrolyte and not a neurotransmitter. Cholinesterase breaks down acetylcholine and is an enzyme, not a neurotransmitter. Monoamine oxidase is an enzyme that breaks down norepinephrine.

Answer to Question 2

D
Feedback:
The nerve axon, called the presynaptic nerve, releases a chemical called a neurotransmitter into the synaptic cleft; the neurotransmitter reacts with a very specific receptor site on the postsynaptic cell to cause a reaction that increases synaptic transmission. Enzymes break down the neurotransmitter. The synaptic transmission is an electrical impulse. Calcium is an electrolyte but does not increase synaptic transmission.
