So once again, the opening of these channels will make the membrane much more permeable to sodium ions than to potassium ions. And the high influx of sodium into our cytoplasm, the cell will make the inside of the cell positive and the outside negative. And this will reverse the polarity. 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?
