Question

Quizplus · Accepted Answer

Alcohol suppresses the release of glutamate, which is the brain's main excitatory neurotransmitter. This results in slowed brain activity and can cause the sedative effects associated with alcohol consumption. GABA (choice C) is actually the brain's main inhibitory neurotransmitter and alcohol enhances its effects, leading to further CNS depression. 5-HT (serotonin) (choice A) and dopamine (choice B) are not directly affected by alcohol, although alcohol can indirectly impact their levels through its effects on other neurotransmitters and brain systems.
