We're going to be looking at channel proteins and what it is that makes them fast and slow.
00:07
Specifically, we're going to be looking at sodium and potassium channel proteins.
00:15
Focusing in on one aspect at a time, first we are going to look at two different ways that these channel proteins can be used.
00:27
You can have active slash deactive mode or you can have inactive mode and de -inactive mode.
00:39
The deactive and inactive are distinct.
00:43
You don't want to get them confused.
00:45
In the active and deactive mode, we have this channel protein.
00:50
On one side, you have this sort ball and chain, which is a method of closing, but that one's not the one used here.
00:57
Instead, we're using this part right here.
01:01
This part can come up and just kind of close the entrance.
01:06
This is considered a fast acting trigger.
01:12
It can just come up, close the entrance, or lay back down and leave it open.
01:17
If it's down like it is in the original picture, then it is active...
