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) 50
B) 100
C) 150
D) 200
As we knw that ATP molecule allows 3 Na+ to move out of the cell and 2 K+ will definitely enter. So as a result 50 ATP molecules allow 150 Sodium ions to move out and therefore allows 100 Potassium ions to move in so i conclude option C is correct hope it helps
