What is the function of the sodium potassium ion pump?

Question

What is the function and purpose of the sodium/potassium ion pump?  What type of transport is used in the process?

Answer 1

A sodium-potassium pump is a special transport protein in the plasma membrane of animal cells that transports sodium out of the cell and potassium into the cell against their concentration gradients. It requires ATP. The movement of these ions is not by simple diffusion from a high concentration but AGAINST it.
