← Human Body & HealthIf a drug selectively blocks the reuptake transporter for dopamine at the synapse, which consequence follows?
A)Decreased dopamine production by neuron
B)Reduced dopamine binding to postsynaptic receptors
C)Prolonged dopamine signaling in synapse✓
D)Increased degradation of dopamine in vesicles
💡 Explanation
Blocking reuptake prevents dopamine from being cleared from the synapse. This prolongs its interaction with postsynaptic receptors, because the dopamine remains in the synaptic cleft longer, rather than being transported back into the presynaptic neuron or degraded.
