Question

What happens to acetylcholine after it attaches to a receptor on the postsynaptic cell?​ Select one: a. ​It is metabolized by the postsynaptic cell as a source of energy. b. ​It is reabsorbed intact by the presynaptic cell. c. ​It continues to stimulate the postsynaptic neuron until replaced by another neurotransmitter. d. ​It is broken down into two components.

Answer 1

Answer: ​It is broken down into two components.

Step-by-step explanation:

On attachment of acetylcholine to a cholinergic receptor at the postsynaptic cell, an enzyme named CHOLINESTERASE renders the ACETYLCHOLINE inactive by breaking it into two components; thereby preventing it from accumulating at the synaptic gap, and enabling the reestablishment of resting potential at the first neuron.
