Metabolism Review Amplify

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

• Yes, as long as her cells have enough oxygen, her body will be able to exercise.

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

• No, her cells need amino acids to react with oxygen to release enough energy to exercise.

• No, her cells need glucose to react with amino acids to release enough energy to exercise.

Jamal ate a meal of rice before seeing his doctor. Rice is made of mostly starch molecules. Jamal has been feeling tired a lot, so his doctor gave him a test that found that Jamal’s cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired?

• Yes, Jamal’s respiratory system is working, but his digestive system is not turning the oxygen into glucose.

• Yes, Jamal’s respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.

• Yes, Jamal’s digestive system is working, but his respiratory system has too much oxygen, so his body stopped making energy.

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

A patient has been eating healthy foods, but her respiratory system is not working as well as it usually does. Can this patient still exercise normally?

• Yes, her body can get everything it needs for energy from molecules in food.

• No, her respiratory system does not have enough oxygen to combine together to release energy

• No, her cells do not have enough oxygen to react with glucose and release energy.

• No, her cells do not have enough oxygen to react with proteins to release energy
