Potassium Channels Are Now Open

Sodium channels will close earlier, but the potassium channels should open it around about positive 30. So this key opens up voltage gated potassium channels now. Most of the sodium is now inside the neuron, right? When it was previously outside the neuron. But here's the problem. We may now have repolarized the cell. Bit too far. It's negative. Potassium channels didn't close earlier enough. And we lost too much potassium and too much charge mainly.
