Q: During the action of a sodium-potassium pump, 50 ATP molecules were spent. Predict how many sodium ions are transported across the cell membrane.
A: ATP molecule allows 3 Na+ to move out of the cell and 2 K+ to enter. So 50 ATP molecules allow 150 Sodium ions to move out and 100 Potassium ions to move in.
The answer is: 150
