Answer:
The repolarization phase of an action potential results from <u>the opening of voltage-gated K channels.</u>
Explanation:
Repolarization is the change in the potential of the membrane of the neuron. It returns the membrane to the negative value which was changed to a positive value during depolarization. During repolarization, the sodium channels are slowly closed and the potassium channels open up. The potassium channels are voltage-gated.
Depolarization causes a positive change in the membrane potential by opening the sodium channels and closing the potassium channels. The opening of the sodium and potassium channels aids in the depolarization and repolarization along with the closing of potassium and sodium channels respectively.
