2.2

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.

Kalila 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 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.
