E) open in response to changes in the membrane potential and are responsible for the generation of the action potential in neurons

Question

Quizplus · Accepted Answer

Voltage-gated ion channels open in response to changes in the membrane potential and are responsible for the generation of the action potential in neurons. This is because they allow for the influx of positively charged ions (such as sodium) into the cell, which depolarizes the membrane and triggers the action potential.
