POINT!
| The Na-K pump moves potassium (K+) from outside to the inside, and sodium (Na+) from the inside to the outside of the cell. |
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.
