Na-K ATPase
Correct Answer: 3 Na out / 2K in
Description: Na+-K+ATPase, which actively moves Na+and K+ against their electrochemical gradient. The electrogenic Na K ATPase plays a critical role in cellular physiology by using the energy in ATP to extrude 3 Na+ out of the cell in exchange for taking two K+ into the cell.
