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.

Challenge Quiz

1.

The Na-K pump is located in the nucleus on the cell membrane inside the cytoplasm .

2.

The Na-K pump moves Na+ from inside to the outside from the outside to the inside of the cell.

3.

The Na-K pump moves K+ from inside to the outside from the outside to the inside of the cell.

4.

Because of the Na-K pump, the concentration of K+ is higher outside inside the cell.

5.

Because of the Na-K pump, the concentration of Na+ is higher outside inside the cell.
