Despite its dangers, a young man continues to take cocaine because of the feeling of euphoria it produces for him. This powerful arousal of his nervous system is probably due to cocaine's ability to
A) inhibit enzymes that break down neurotransmitters.
B) increase the release of neurotransmitters.
C) block the receptor sites for neurotransmitters.
D) prevent neurotransmitters from being reabsorbed into presynaptic terminals.
Answer: D
Rationale: Cocaine blocks reuptake of dopamine by binding to presynaptic terminals. By blocking reuptake of dopamine cocaine allows excess amounts of this neurotransmitter to remain in the synapse and continue binding with postsynaptic receptors.
