While the membrane is depolarizing its sodium gates are fully open.
Step-by-step explanation:
Depolarization is when the membrane potential shifts limited negative (extra positive). Depolarization and hyperpolarization transpire when ion ways in the membrane open or close, adjusting the capacity of particular sorts of ions to penetrate or exit the cell.
Depolarization transpires when a motive arrives a relaxing neuron. There is a great density of voltage-gated Na+ channels so that speedy depolarization can obtain here. While the depolarization stage, the gated sodium ion channels on the neuron’s membrane abruptly open and release sodium ions (Na+) grant outside the membrane to hurry into the cell.
