sodium-potassium pumpThe mechanism of cell action potential(AP)was explained by using the principle of potassium channel"origami windmill"model.It is inferred that ion channels should include at least two categories:one kind of channel is"special ion channel",whose structure is like an origami ...
Action potential, the brief (about one-thousandth of a second) reversal of electric polarization of the membrane of a nerve cell (neuron) or muscle cell. In the neuron an action potential produces the nerve impulse, and in the muscle cell it produces the

the sodium/potassium pump why is it a good thing that VGPC are slow? it ensures that they open after Na channels otherwise you won't get the right action potential shape. they also close slowly and remain open even after the AP has repolarised. ...
The sodium-potassium exchange pump: A) must re-establish ion concentrations after each action potential. B) transports sodium ions into the cell during depolarization. C) transports potassium ions out of the cell during repolarization. D...
