Channels that open or close depending on local potential changes are called:
A) voltage-gated ion channels.
B) depolarization channels.
C) sodium-potassium pumps.
D) ligand-gated ion channels.

Question

Quizplus · Accepted Answer

Voltage-gated ion channels open and close in response to changes in membrane potential or voltage, allowing ions to flow in or out of the cell. The other options (B, C, and D) do not specifically refer to channels that open or close based on membrane potential changes.
