The principle inhibitory neurotransmitter, __________, works by triggering an influx of ______ causing hyperpolarization of nerve cells. A)$\gamma$-aminobutyric acid; K⁺ B)$\gamma$-aminobutyric acid; Cl^- C)serotonin; K⁺ D)serotonin; Cl^- E)none of the above

Question

Quizplus · Accepted Answer

The principle inhibitory neurotransmitter is gamma-aminobutyric acid (GABA). GABA triggers an influx of chloride ions (Cl-) causing hyperpolarization of nerve cells, which makes it harder for the neuron to produce an action potential. Therefore, option B is the correct answer as it mentions GABA and Cl-.
