WebIn nervous system: Repolarization. This is called sodium inactivation, and it is caused by gates within the channel that are sensitive to depolarization. Following sodium inactivation is the opening of potassium channels, which allows the diffusion of K + out of the cell. WebIn the open state, voltage-gated sodium channels form a pore in the cytoplasmic membrane that allows sodium ions to flow into the cell, depolarizing the cell and …

WebThe falling phase of the action potential is caused by the inactivation of the sodium channels and the opening of the potassium channels. After approximately 1 msec, the sodium channels inactivate. The channel becomes blocked, preventing ion flow. At the same time, the voltage-gated potassium channels open.
