WebNeurotransmitters who’s activities are terminated by reuptake include dopamine, serotonin, norepinephrine, epinephrine, and glutamate. Reuptake happens because the sending neuron has transporter proteins that face the synaptic cleft. These transporter proteins are symporters, meaning they pump both a salt ion and a neurotransmitter back into ... WebRelease of NT Step 1. A population of synaptic vesicles become docked against the presynaptic membrane before spilling their contents into the synaptic cleft. …

Neurotransmitter release occurs at synapses, which are the sites of transmission of electric nerve impulses between two neurons or between a neuron and a gland or muscle cell.
WebNeuropeptides are synthesized in the cell body and must be transported to the terminal, which can lead to slower release. Additionally, a neuron typically will synthesize and release only one type of small molecule neurotransmitter but can synthesize and release more than one neuropeptide. Small Molecule Transmitters
