The Na⁺ and K⁺ channels that open during an action potential are voltage-regulated, both opening in response to depolarization of the membrane.

Question

Quizplus · Accepted Answer

Both Na⁺ and K⁺ channels are voltage-gated channels, meaning they open in response to changes in membrane potential. Specifically, they open in response to depolarization of the membrane during an action potential.
