The extent of neurotransmitter binding to receptors on the postsynaptic membrane is determined primarily by which of the following?
A) sodium
B) the concentration of neurotransmitter
C) neurotransmitter vesicles
D) calcium
E) the distance of the cleft

Question

Quizplus · Accepted Answer

The concentration of neurotransmitter in the synaptic cleft primarily determines how much neurotransmitter can bind to receptors on the postsynaptic membrane. Higher concentrations increase the likelihood of neurotransmitter molecules binding to receptors, influencing the strength of the signal transmitted.
