Question

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

Answer 1

I think the correct answer from the choices listed above is option C. There would be 150 sodium ions that will be transported across the cell membrane.  Each ATP molecule aids in moving 3 Na+ across the membrane. So, 50 times 3 is equal to 150.
