Answer
6. ANS. c. Release of neurotransmitter into the synaptic cleft
Work Step by Step
In this kind of ligand gated transmission, the action potential causes voltage-gated release of neurotransmitter from synaptic vesicles in the axon terminal buttons where it is are stored. The ligand molecules cross the synaptic cleft and are picked up by neurotransmitter receptors on postsynaptic membranes of dendrites or cytons.
