D.Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
The correct option is D.
Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
Explanation:
Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells because there is no need for enzymes and the whole digestive system to digest the glucose , this is because glucose is the end product of carbohydrates digestion i.e it is breakdown into glucose which is in a form the body can easily absorb it to the cells.
Since the body can absorb it to the cells, it will supply her with the energy she needed easily and her ability to exercise will remain the same because when you exercise the body does not use energy from digestion rather it slows digestion and divert the blood to the muscles and lungs to exercise.
