sodium-potassium pump

[Herst]

I understand that ATP supplies the energy which drives the pump, but I am unclear to how it works. Sodium ions leave the cell, while potassium ions enter the cell; is this through a nuclear pore, or an enzyme, or what? Any help in helping clarify this topic would be appreciated... Thanks

This is also an example of one type of Active transport.

Hi Everybody,
This is Stephen, sodium is poisonous to cells so they pump it out. then they pump potassium in to balance the change and osmotic pressure.even if the sodium/potassium pumps are inactive neurons can fire hundreds of thousands of times.
