In fact, we actually have these potassium ion channels that are open within that membrane. And if we have some of these potassium ion channels open along that resting membrane, what that means is we'll have a movement, a leakage of these K plus ions out of that cell. And that leakage will basically drive this value to a more negative value. It will basically decrease it. And that's exactly why the actual resting membrane potential is actually way closer to this value than to this value because of those K plus ion channels. So because the potassium ion channels are actually open, some of them are open.
