Explanation:
Detailed explanation-1: -The molecules of neurotransmitter diffuse across the synaptic cleft and bind to receptor proteins on the postsynaptic cell.
Detailed explanation-2: -As a result of the action potential, the chemical transmitter acetylcholine (ACh) is released into the synaptic cleft. ACh diffuses across the synaptic cleft and binds to special receptors on the postsynaptic or the postjunctional membrane.
Detailed explanation-3: -Once they have been released and have bound to postsynaptic receptors, neurotransmitter molecules are immediately deactivated by enzymes in the synaptic cleft; they are also taken up by receptors in the presynaptic membrane and recycled.
