Which of the following sequences of steps best represents the order of events that occur during synaptic transmission?
A)binding of neurotransmitter at the postsynaptic membrane → diffusion of neurotransmitter across the synapse → release of neurotransmitter from the presynaptic cell
B)diffusion of neurotransmitter across the synapse → binding of neurotransmitter at the postsynaptic membrane → release of neurotransmitter from the presynaptic cell
C)release of neurotransmitter from the presynaptic cell → binding of neurotransmitter at the postsynaptic membrane → diffusion of neurotransmitter across the synapse
D)release of neurotransmitter from the presynaptic cell → diffusion of neurotransmitter across the synapse → binding of neurotransmitter at the postsynaptic membrane

Question

Quizplus · Accepted Answer

The release of neurotransmitter from the presynaptic cell occurs first, followed by diffusion across the synapse, and finally binding of neurotransmitter at the postsynaptic membrane. This sequence of events is necessary for neuronal signaling to occur, as the release of neurotransmitter is what triggers communication between the pre- and postsynaptic cells.
