Sodium-Kpump-e.jpg

The sodium (Na+)-potassium (K+) pump moves potassium (K+) from outside to inside the cell, and sodium (Na+) from inside to outside of the cell.  As a result of this pump, the concentration of potassium (K+) is higher inside the cell, and the concentration of sodium (Na+) is higher outside the cell.
