E) threshold

Question

Quizplus · Accepted Answer

The level of membrane depolarization required to induce the sodium channel's positive feedback loop is called the threshold. When the membrane potential reaches this level, it triggers the opening of voltage-gated sodium channels, leading to further depolarization and the propagation of an action potential.
