Metabolism

An athlete thinks that she can exercise as long as she eats different types of food because her body just needs different types of food molecules to work properly. Is the athlete correct?

• A Yes, her cells only work when they have molecules from different types of food.

• B No, her muscles do not need molecules from food because all cells make all the molecules they need.

• C No, all cells need molecules from food and molecules from air to work properly.

• D No, only her stomach cells need food molecules to work properly.

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?

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

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

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

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

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

• A Yes, her cells just need to combine amino acids to release energy.

• B No, her cells need to combine glucose into starch molecules to release energy.

• C No, her cells need glucose to react with oxygen to release energy.

• D Yes, her cells just need oxygen to release energy.
