Question

question 7 (2 points)
alcohol acts on all of the following neurotransmitters, except:
a) gamma - amino - butyric acid (gaba).
b) glutamate.
c) adrenaline.
d) acetylcholine.
question 8 (2 points)
alcohol acts on the central nervous system as a:
a) stimulant.
b) depressant.
c) hallucinogen.
d) sympathomimetic.

Explanation:

• Question 7: Alcohol affects GABA (enhances its inhibitory effects), glutamate (reduces its excitatory effects), and acetylcholine. Adrenaline is not a neurotransmitter that alcohol primarily acts on in the context of its main neuro - transmitter interactions.
• Question 8: Alcohol depresses the central nervous system. It slows down neural activity, which is characteristic of a depressant. Stimulants increase neural activity, hallucinogens cause perceptual distortions, and sympathomimetics mimic the effects of the sympathetic nervous system (not the main action of alcohol on the CNS).

Answer:

• Question 7: C. adrenaline
• Question 8: B. depressant
