Acetylcholine is the neurotransmitter in the cholinergic neurons. What is the precursor that acetylcholine is derived from?
High-Yield Explanation
The conversion of choline by CAT (choline acetyltransferase) is responsible for conveing choline to acetylcholine. Likewise, the conversion of acetylcholine back to choline is by ACH-ase (acetylcholine esterase). CAT ACh-ase Choline ----> Acetylcholine ----------> Choline
