Consider the following situation: a. A cell contains 3 Na⁺, 7 K⁺, and 10 H₂O molecules. b. The extracellular fluid contains 7 Na⁺, 3 K⁺, and 10 H₂O molecules. c. All ions create equal osmotic pressure. d. The cell membrane is impermeable to the diffusion of both Na⁺ and K⁺ but is completely permeable to H₂O. If 3 Na⁺ move from the ICF out if the ECF, then a. Is the ECF now isotonic, hypotonic, or hypertonic to the ICF? b. How must the Na⁺ have gotten outside the cell? c. If osmosis is also going to occur, in which direction will the net movement of water be?

If three sodium ions move from the ICF into the ECF, the ECF is now hypertonic to the ICF. The sodium ion got out of the cell through the sodium-potassium pump, which is a membrane-associated protein channel that uses ATP to move sodium and potassium ions against their concentration gradient. Two potassium ions are moved into the ICF for every three sodium ions that leave the cell. If osmosis is also going to occur, the direction of the net movement of water will be from the ICF to the ECF.
