During an action potential, which of the following is directly responsible for restoration of resting membrane potential? A) efflux of K⁺ ions B) efflux of Na⁺ ions C) influx of K⁺ ions D) influx of Na⁺ ions E) efflux of Cl− ions

Question

Quizplus · Accepted Answer

During an action potential, efflux of K+ ions is directly responsible for restoration of resting membrane potential. As the action potential reaches its peak, voltage-gated K+ channels open and allow K+ ions to flow out of the cell, leading to repolarization of the membrane and restoration of its resting potential.
