Neurotransmitters are formed in a presynaptic neuron and stored in small membrane-bound sacks, called vesicles, inside this neuron. When this neuron is activated, these intracellular vesicles fuse with the cell membrane and release their contents into the synapse, a process called exocytosis.
As a rule, the synthesis of small-molecule neurotransmitters occurs within presynaptic terminals (Figure 6.6B). The enzymes needed for transmitter synthesis are synthesized in the neuronal cell body and transported to the nerve terminal cytoplasm at 0.5â5 millimeters a day by a mechanism called slow axonal transport.he mechanisms responsible for the synthesis and packaging of peptide transmitters are fundamentally different from those used for the smallmolecule neurotransmitters (Figure 6.6C). Peptide-secreting neurons generally synthesize polypeptides in their cell bodies that are much larger than the final, âmatureâ peptide.
