5. A red blood cell made up of 9% potassium and the surrounding plasma which contains 5% potassium, the plasma is                                                                                                                to the cell.

6. A red blood cell made up of 15% potassium has a sodium potassium channel that moves the potassium ions across the cell membrane. If the surrounding plasma which contains 35% potassium, then the plasma

is                                            to the cell.

7. A red blood cell made up of 15% potassium has a sodium potassium channel that moves the potassium ions across the cell membrane. If the surrounding plasma which contains 35% potassium, which way will the solute move?

8. The movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy is called:

9. Diffusion of water through a semi permeable membrane called:
