Hi, Thanks For Your Question.
Answer : The Opening And Closing Of Of Voltage Gated Na+ and k+ channels Occurs During Action Potential. Action Potential Is A Signal In The Form Of Electrical / Ionic Currents Which Is Caused By Change On Polarity Of Membrane Potential.
Explanation :
Normally, Cell Membrane Is In Resting Membrane Potential I.e The Ionic Concentration Of Sodium and chloride Are Lower Inside the cell Than Outside, And The Ionic Concentration Of Potassium Is Greater Inside The Cell.This concentration Differences Ions Is Due To Action Of a Membrane Transport system Which Pumps Sodium Out of The cell and Potassium Inside The Cell.
