FREE Expert Solution

The refractory period for voltage-gated channels helps in maintaining operational integrity of the channels. Since these channels are voltage-gated, they open upon reaching the threshold membrane potential. However, these won't close until resting potential is restored and the resting potential cannot be restored unless the flow of ions stop.
