Question

cocaine blocks the reuptake of ________. a glutamate b acetylcholine c gaba d dopamine

Explanation:

Cocaine primarily acts by blocking the reuptake of dopamine. When cocaine is in the system, it binds to dopamine transporters, preventing dopamine from being reabsorbed by the presynaptic neuron. This leads to an accumulation of dopamine in the synaptic cleft, which is associated with the euphoric effects of cocaine. Glutamate is an excitatory neurotransmitter involved in learning and memory. Acetylcholine is important for muscle control and memory. GABA is an inhibitory neurotransmitter. But cocaine's main impact is on dopamine reuptake.

Answer:

D. dopamine
