Question

Quizplus · Accepted Answer

Neuropeptides are synthesized in the cell bodies of neurons, unlike many other neurotransmitters that are synthesized in the axon terminals. This is because neuropeptides are synthesized as larger precursor proteins on ribosomes and then processed into their active form, a process that occurs in the cell body before they are transported to the axon terminals.
