And that's because now these become inactivated. So as a result of this ball, it basically goes into that pore and then inactivates that protein. And it basically prevents the movement of those ions across the cell membrane. And that happens here. At the same exact time, those voltage gated potassium ions that were slow to open, now open up much, much quicker. And so, because we have the closure of these and the opening of the potassium voltage gate on challenge, now the positive charge begins to move out of the cell.
