Sodium-Potassium pump

Post by Daniel01 » Wed Nov 19, 2008 5:45 pm

The role of absorption of glucose involves the sodium-potassium pump being used along with facilitated diffusion and active transport, what does the potassium ion actually do in the process?

Potassium is a part, if I can so say, of na/p -ATPzase. This ATPase transport 2K+ ions in the cell and 3 na+ ions out of the cell. This Na gradient is used to transport glucose. So without potassium would be no Na+ gradient.
