Final answer:
Conventional neurotransmitters are synthesized in the presynaptic neuron, released into the synaptic cleft, and activate receptors on the postsynaptic membrane to transmit signals between neurons.
Step-by-step explanation:
Conventional neurotransmitters are synthesized in the presynaptic neuron and are released into the synaptic cleft. They activate receptors on the postsynaptic membrane, which triggers a response in the target cell. After activation, neurotransmitters can be recaptured by the presynaptic neuron through reuptake, degraded by enzymes, or diffuse away from the synapse. These neurotransmitters bind to specific receptors on the postsynaptic membrane to relay the signal from one neuron to another.
