Question

1. 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? it would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together. it would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do. 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. 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:

1. Analyze the first option: Glucose is a monosaccharide, and the digestive system doesn't need to combine glucose molecules (it breaks down larger molecules into glucose). So this option is incorrect.
2. Analyze the second option: Glucose's movement speed through the circulatory system isn't the main reason for easier exercise; rather, it's about cellular respiration. So this option is incorrect.
3. Analyze the third option: Glucose doesn't have more energy than oxygen, and the respiratory system's work is related to gas exchange for respiration, not directly to glucose's energy comparison. So this option is incorrect.
4. Analyze the fourth option: Glucose is a simple sugar (monosaccharide) that can be directly absorbed into the bloodstream and used by cells for energy. So the digestive system doesn't need to break it down further, reducing its workload, and it doesn't affect exercise ability negatively (in fact, glucose is a quick energy source). This option is correct.

Answer:

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. (Note: Assuming the options are labeled A, B, C, D as per the order, with the last option being D)
