Hello everyone.
00:01
Today we are going to be talking again about voltage gated channels and action potential.
00:07
So this is the drawing of a voltage gated channel right here from my last video if you watched it.
00:15
So when there's the cells polarized, there's sodium all on the outside and potassium all on the inside.
00:31
Okay.
00:32
So this is extracellular.
00:39
This is the plasma membrane.
00:41
And this is intracellular or the cytoplasm.
00:47
Okay.
00:48
So when an action potential comes through, okay, these are closed.
00:54
The voltage gated channels are closed.
00:56
There's nothing coming through.
00:58
When an action potential comes through, it depolarizes this membrane...
