The effects of ethanol on the brain arise in part from opening of ____ receptor Cl− channels.
A) glycine
B) aspartate
C) glutamate
D) γ-aminobutyrate (GABA)
E) all are true

Question

Quizplus · Accepted Answer

Ethanol enhances the activity of the γ-aminobutyrate (GABA) receptor, which leads to an increase in Cl- ion influx and hyperpolarization of the neuron. This results in sedative effects and impairment of cognitive and motor functions. Ethanol also inhibits the activity of excitatory receptors such as glutamate and aspartate, but it does not directly affect glycine receptors.
