Sagot :
The voltage-gated sodium channels would be mostly open at the peak of the action potential, while the voltage-gated potassium channels would be mostly closed.
At this point, the membrane potential has reached its maximum depolarization, and thus Na+ channels are maximally activated. However, K+ channels are beginning to close as the membrane potential starts to repolarize. Thus, more Na+ ions are entering the cell than K+ ions are exiting, leading to a further depolarization of the membrane. Influx of sodium ions into the cell causes the cell to become depolarized. Once the cell reaches its threshold potential, the voltage-gated potassium channels open, allowing for the efflux of potassium ions out of the cell. This causes the cell to become repolarized.
