Metabolism

Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul’s cells contained glucose molecules, but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?

• No, something else must be wrong because his cells have all the molecules they need.

• Yes, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.

• Yes, his respiratory system is working, but his digestive system is not getting energy from combining glucose molecules.

• Yes, his digestive system is working, but his respiratory system is not breaking down oxygen, so his body stopped making energy.

Doctors tested a patient to find out what molecules were in his cells. His cells contained normal levels of glucose molecules and amino acid molecules, and low levels of oxygen molecules. Will this patient be able to exercise normally?

• Yes, his body is working properly enough to exercise.

• No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.

• No, his body systems are working, but he needs to eat different food; only proteins can react with glucose to release energy.

• No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.

Marisol has been chewing and swallowing her food, but her digestive system is not doing what it usually does. Why is this a problem for her ability to exercise?

• Her cells will not work well because molecules from her food are not being broken down small enough to get to her cells.

• Her body will run out of energy because molecules from the air are not being combined into larger molecules for the cells.

• Her respiratory system will have to work twice as hard to break down molecules from food.

• Her cells will not work well because the molecules from food will be too small for cells to use.
