Question

Quizplus · Accepted Answer

Alcohol is known to alter the fluidity of neuronal membranes by interacting with the hydrophobic regions of lipid bilayers, which can affect the function of ion channels and neurotransmitter receptors.

Answer: B 
 Alcohol can act as a presynaptic stimulant by enhancing the release of certain neurotransmitters, particularly GABA.

Answer: C 
 Alcohol can interfere with the reuptake of certain neurotransmitters, particularly dopamine, which can lead to increased synaptic concentrations and prolonged effects on postsynaptic receptors.

Answer: D 
 Alcohol has been shown to have inhibitory effects on monoamine oxidase, which is an enzyme that breaks down neurotransmitters such as dopamine, serotonin, and norepinephrine. This leads to increased levels of these neurotransmitters in the synapse, which can contribute to the overall effects of alcohol on behavior and cognition.
