Kaelyn Ingram · Answer 1

depolarization leading to action potentials

Explanation:

The voltage-gated Na + channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na + channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.
