Updated On: Apr 9, 2025
- Acetylcholine
- Serotonin
- GABA
- Dopamine
Hide Solution
Verified By Collegedunia
The Correct Option is D
Approach Solution - 1
Cocaine interferes with dopamine transport by blocking its reuptake, increasing dopamine levels in synapses (causing euphoria).
- (A) Acetylcholine: Not directly affected by cocaine.
- (B) Serotonin: Targeted by drugs like SSRIs, not cocaine.
- (C) GABA: Inhibitory neurotransmitter, unrelated to cocaine’s mechanism.

Approach Solution -2
Cocaine blocks dopamine reuptake in the brain’s reward pathway, causing euphoria and addiction.
Dopamine is a neurotransmitter, a chemical messenger in the brain that plays a key role in many important functions, including mood regulation, motivation, pleasure, reward, and motor control. It is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area.
Other neurotransmitters:
- (A) Acetylcholine: Muscle activation.
- (B) Serotonin: Mood regulation.
- (C) GABA: Inhibitory signals.
Correct Answer: (D) Dopamine
