Based on the two-step model of glucose transport, what would happen if the supply of ATP was depleted from the cell? The sodium-potassium pump would make less of a sodium gradient, but it would have no effect on the glucose transport. The sodium-potassium pump would be unaffected, and therefore, there would be no effect on glucose transport. The sodium-potassium pump would make less of a sodium gradient, so less glucose could be transported across the membrane. The sodium-potassium pump would be unaffected, but the rate of glucose transport would increase.
