Question

Quizplus · Accepted Answer

Drug antagonists work by blocking or dampening biological responses. Choices A, B, and D describe mechanisms that would prevent a neurotransmitter's action or availability, acting as antagonists. Choice C, which blocks the reuptake of a neurotransmitter, would increase the neurotransmitter's availability in the synaptic cleft, enhancing its action rather than antagonizing it. This mechanism is typical of drug agonists, not antagonists.
