One difference between the ion channel-linked receptors for GABA and acetylcholine is that when GABA binds its receptor:
A) muscle contraction is inhibited.
B) sodium ions enter the cell.
C) muscle contraction is stimulated.
D) neural signaling is inhibited.
E) chloride ions rush out of the neuron.

Question

Quizplus · Accepted Answer

When GABA binds to its ion channel-linked receptor, it typically results in the opening of chloride channels, leading to an influx of chloride ions into the neuron. This hyperpolarizes the neuron, making it less likely to fire an action potential, thereby inhibiting neural signaling.
