Hello,
I’m wondering why in an action potential, the Na+ go into the cell and K+ go out of the cell, but in the resting potential and Na+/K+ pump, the Na+ go out and K+ go in? Why does the direction of Na+ flow switch?
Thanks!

Hello Nicole,
In an action potential, it requires energy to drive Na and K against their natural electro-chemical gradient to change the resting membrane potential. At resting the molecules are flowing down their natural gradients.
Thanks,
Kennedy
