Synaptic Transmission

Item #5 of 10

Following the initiation of an action potential on the postsynaptic membrane the _______________.

presynaptic membrane will automatically depolarize;

neurotransmitters may be taken up by the presynaptic membrane for reuse;

postsynaptic membrane will synthesize more neurotransmitters;

the neurotransmitters will be reactivated in the synaptic cleft;

none of the alternatives is correct;

INCORRECT - Depolarization of the presynpatic membrane is dependent upon the incidence of action potentials that may occur in the aftermath of any given synaptic transmission.
