Name two neurotransmitters and one main function each.

• A. Acetylcholine—memory consolidation; Norepinephrine—emotion processing
• B. Dopamine—reward/movement; Serotonin—mood regulation
• C. Endorphins—pain relief; Dopamine—autonomic control
• D. Dopamine—sleep regulation; GABA—edge of pain modulation

Answer: (B)

Neurotransmitters have well-established, memorable roles in brain signaling. Dopamine is best known for its involvement in reward and movement, helping reinforce rewarding behaviors and coordinating motor control through key brain circuits. Serotonin is most closely linked to mood regulation, shaping emotional state and affect, with additional roles in sleep and appetite but commonly cited for its influence on mood.

Other pairings either mix less central functions or pair a neurotransmitter with a description that isn’t its clearest, most widely recognized role. This makes the combination in dopamine and serotonin the most straightforward and accurate answer for two neurotransmitters with one main function each.
