So it will depolarize our cell membrane, because before, we have negative charge inside, now we have a positive charge inside. Now, so the inside of the cell will become positive. But what exactly is the magnitude of our positive charge? Well, when the inside of the cell reaches a positive voltage of about positive 45 million volt at this point, this will signal our voltage gated sodium channels to close. And at the same time, it will signal the voltage gated potassium channels to actually open up. And at this point, this basically ends depolarization, and it starts repolarization.
