During an Action Potential,which Happens First

Question

During an action potential,which happens first?
A)opening of voltage-gated Na⁺ channels
B)closing of voltage-gated Na⁺ channels
C)opening of voltage-gated K⁺ channels
D)closing of voltage gated K⁺ channels

Accepted Answer

During an action potential, the opening of voltage-gated Na⁺ channels occurs first, leading to an influx of Na+ ions into the cell, causing depolarization.
