Which of the following statements best describes the immediate consequence of neurotransmitter molecules binding to ligand-gated ion channel receptors?
A)Voltage-gated channels in the cell membrane open and permit ion flow through the membrane.
B)The activity of the sodium-potassium pumps increases.
C)Calcium absorption into the axon terminal cell is triggered.
D)Neurotransmitter-containing vesicles bind to the inside of the axon terminal membrane.

Question

Quizplus · Accepted Answer

When neurotransmitter molecules bind to ligand-gated ion channel receptors, the ion channel opens and allows the flow of ions through it, leading to changes in membrane potential and initiation of an action potential. This is known as synaptic transmission. The other options given describe other cellular processes that are not directly related to neurotransmitter binding to ligand-gated ion channels.
