Depolarization
|
Explanation:
Detailed explanation-1: -Repolarization. In response to the inflow of Na +, K + channels open, this time allowing K + on the inside to rush out of the cell. The movement of K + out of the cell causes repolarization by restoring the original membrane polarization.
Detailed explanation-2: -Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels. Repolarization is caused by the closing of sodium ion channels and the opening of potassium ion channels.
