Which of the following is responsible for the repolarization of the membrane after the peak of the action potential? A)The membrane potential reaches the Na⁺ equilibrium potential. B)The voltage-gated Na⁺ channels begin to inactivate. C)The slowly opening voltage-gated K⁺ channels allow K⁺ to enter. D)The influx of Na⁺and the outflow of K⁺are equal. E)There is no longer a gradient to drive K⁺ out of the cell.

Question

Quizplus · Accepted Answer

The inactivation of voltage-gated Na⁺ channels and the opening of voltage-gated K⁺ channels allow K⁺ to exit the cell, leading to repolarization.
