Buckle up for this real quick introductory journey that i know you want to take, where we are talking about the sodium and potassium pump, which is in a lot of our cells.
00:11
So this is mostly used in the nervous system and in our neurons.
00:16
And essentially the sodium and potassium pump pushes those elements against their gradient, so the cell has everything that it needs to do the job that it needs to do.
00:29
Okay, so i'm gonna draw the sole shape.
00:34
This is our sodium potassium pump here, which is inside of the plasma membrane.
00:41
Okay, so we're gonna start by looking at sodium.
00:43
So naturally there's a lot of sodium out here, and there's more sodium out here, but what happens is when the cell needs to, it will have some sodium inside that it wants to push out, so it has the proper ratio of sodium and potassium.
01:03
So we want to get this sodium out, even though that's against the gradient.
01:08
So what's gonna happen is there's gonna be an atp, so some energy out here, that is going to be phosphorylized.
01:17
So it'll turn into a dp, and we'll have a phosphorus that can be attached to the pump...
