The role of calcium ions Ca²⁺) in synaptic transmission is to A) bind neurotransmitter molecules to the postsynaptic membrane. B) mediate the release of neurotransmitter molecules from the presynaptic neuron. C) repolarize the postsynaptic cell after transmission has been completed. D) increase the activity of the sodium-potassium pumps in the presynaptic cell.

Question

Quizplus · Accepted Answer
