C) increase reuptake of the transmitter.
D) provide negative feedback on synthesis or release of transmitter.
E) increase the transmitter synthesis.

Question

Quizplus · Accepted Answer

If a transporter in the presynaptic membrane is inactivated, it will lose its ability to reuptake the transmitter from the synapse back into the presynaptic neuron. This would lead to an accumulation of transmitter in the synapse, increasing the levels of the transmitter in the synapse.
