Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?
a It would be harder for her to exercise because her digestive system would
need to use more enzymes to combine the glucose molecules together.
b It would be easier for her to exercise because glucose moves through the
circulatory system faster than other food molecules usually do.
c Nothing would happen to her ability to exercise, but her respiratory system
would not work as hard, since glucose has more energy than oxygen
molecules.
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.
