During the action of a sodium-potassium pump, 50 ATP molecules are spent. Predict how many sodium ions are transported across the cell membrane.

A. 50
B. 100
C. 150
D. 200

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.

The sodium-potassium pump transports 3 sodium ions for every ATP molecule used. Therefore, if 50 ATP molecules are spent, a total of 150 sodium ions are transported across the cell membrane. The correct answer is option C: 150.
