This video discusses the activation cycle of voltage gated potassium (K+) channels and is a follow up to a previous video I composed on the activation cycle of voltage gated Na+ channels. Because K+ channels share a number of structural/functional similarities with Na+ channels, it would be a good idea to check out Na+ channel video first (unless you are already familiar with the functional/structural features of the voltage gated Na+ channel.

Is not that graph you showed in the beginning of the video related to the sodium voltage channels, that activates the concentration gradient channels after that first curve? Tks! ;-)

So what do you do if your potassium channel is closed

Why are the channels slow to open and close?

what causes the k+ channels to be slow?

Yes, I have the same question! It seems almost like in contrast, the Na gate is 'toggled', like a spring-loaded electric light switch, such that the movement of its voltage sensor has no effect until suddenly it 'snaps' the gate open, whereas in the K gate the force dynamics of the structure is different, such that there is a slowly changing resistance of the gate to open as the voltage sensor is pushed harder and harder by depolarization, perhaps opening the gate a little bit at a time until it's open sufficiently to allow ion flow? I wonder whether it's the SENSOR which is somehow 'retarded' in its motion, or the CONNECTIONS between the sensor & the gate are more 'spongy' (like hydraulic brakes in a car with air in the lines) , or the GATE is itself retarded in some way (like a door's hinges which need oil)?
