Question

Quizplus · Accepted Answer

Cocaine blocks the reuptake of dopamine, causing a buildup of dopamine in the synaptic cleft. This buildup leads to a larger release of dopamine when the neuron is stimulated. Option A is incorrect because monoamine oxidase catabolizes dopamine molecules that are not stored. Option B is incorrect because dopamine molecules stored in the axon terminal are not transported into the synaptic cleft through dopamine membrane transporters. Option C is incorrect because graded and reuse for dopamine synthesis does not occur in axon terminals.
