WebCa comes in synaptic vesicle moves to the presynaptic terminal lets out neurotransmitters into the synaptic cleft these bind to receptors cellular response membrane potential biochemical cascade regulation of gene expression electrical synapse gap junctions between presynaptic terminal and the postsynaptic terminal WebJun 8, 2024 · The binding of a neurotransmitter to its receptor is reversible. As long as it is bound to a post synaptic receptor, a neurotransmitter continues to affect membrane potential. The effects of the neurotransmitter generally lasts few milliseconds before being terminated. The neurotransmitter termination can occur in three ways.
