After serotonin or one of the catecholamine transmitters stimulates the postsynaptic receptor, most of the transmitter molecules:
A) remain on the receptor until other neurotransmitters replace them.
B) are broken into components while still attached to the postsynaptic cell.
C) are metabolized by the postsynaptic cell as a source of energy.
D) are reabsorbed by the presynaptic cell.

Quizplus · Accepted Answer

After neurotransmitters like serotonin or catecholamines stimulate the postsynaptic receptor, most of the molecules are reabsorbed by the presynaptic cell, a process called reuptake. This helps clear the synapse of excess neurotransmitter and prepares the presynaptic cell for the next cycle of neurotransmission.
