Metabolism Chapter 3

Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?

• Yes, the glucose and oxygen molecules can react together to release energy for the body to function.

• 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; in cells, only amino acids can react with oxygen to release energy

• Yes, as long as his cells have glucose, they don’t need anything else to release energy for the body to function.

What effect does more oxygen in your cells have on cellular respiration?

• It harms cellular respiration which decreases the energy cells create

• It harms cellular respiration which increases the energy cells create

• It improves cellular respiration which decreases the energy cells create

• It improves cellular respiration which increases the energy cells create

Two soccer teams, the Bears and the Panthers, played games at the same time in two different locations. The Bears game was played at sea level, where there is a normal amount of oxygen. Before their game, the players on the Bears ate a lunch of mostly starch. The Panthers game was played at very high altitude, where there is less oxygen. The players on the Panthers ate a lunch of starch and protein. Which team probably did better in their game?

• The Bears probably did better because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system.

• The Panthers probably did better because their cells released energy from breaking down protein in the digestive system, which then combined with oxygen in cells.

• The teams did equally well because their digestive systems just need to break down starch into glucose for cells to release energy.

• The teams did equally well because glucose from starch can react with oxygen or proteins to release energy

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.

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.

A patient has been eating healthy foods, but his digestive system is not doing what it usually does. Can this patient still exercise normally?

• Yes, as long as he can still breathe, his cells will have all the molecules they need to release energy.

• No, his digestive system is not breaking down oxygen into molecules small enough to get inside his cells.

• No, molecules from food are not combining together to be large enough for his cells to use.

• No, molecules from food are not getting broken down small enough to get inside his cells.

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.
