True, The action potential period indeed occurs while we wait for all voltage-gated potassium ion channels to shut.
The interval after an electrical impulse is created when the excitable cell is unable to generate another action potential is known as the refractory period. This epoch is divided into two subphases: relative and absolute refractoriness.
This alpha helix in the lipid bilayer moves in response to variations in membrane potential. The nearby S5-S6 helices that make up the channel pore are affected by this movement's conformational shift, which in turn causes the pore to either open or close.
When the membrane potential hits about -55 mV and there is a significant inflow of sodium, resulting in a sudden rise in voltage, all voltage-gated sodium channels open.
