Metabolism Practice Test

The space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. How can the program’s doctors make sure the astronauts’ bodies work well enough to exercise in space?

• The doctors could make sure that the astronauts’ bodies can make enough energy by getting enough sleep.

• The doctors could make sure the astronauts’ stomachs are getting the molecules they need from food and air.

• The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air

• The doctors could make sure the astronauts’ cells are getting different types of molecules from food.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?

• It would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together

• It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.

• Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.

• Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

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.

Some problems with the digestive system make it very difficult for the body to digest enough food. Why would it be harder to exercise when you have a digestion problem like this?

• You would not be able to sleep, which would make you too tired to exercise.

• Your cells would have molecules from air, but would not get enough molecules from food.

• You would need to breathe in a lot more air because your body would have fewer molecules from food.

• You would not get any of the molecules your cells need to exercise.

The test report above shows the level of molecules in different parts of the patient's body. How would you expect this patient to do on an exercise test?

• Well; his body is working properly.

• Poorly; his digestive system is not combining glucose molecules together for the cells to use.

• Poorly; his digestive system is not breaking down molecules from food into glucose.

• Poorly; his respiratory system is not breaking down oxygen molecules into glucose.

Stella’s respiratory system is not working well. Why is this a problem for her ability to exercise?

• Her respiratory system will not be able to break down molecules from air into oxygen.

• Her cells will not work well when they have low levels of oxygen.

• Her digestive system will have to work twice as hard to get the same amount of energy from glucose molecules

• Her cells will not work because molecules from air will be too large for her body to use.

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.

Asthma is a condition in which it can be very hard for a person to breathe in enough air. Would it also be difficult for someone with asthma to exercise?

• No, as long as the person is getting enough sleep, he will make enough energy to exercise.

• No, as long as the person’s cells are getting different types of molecules from food, he can still exercise

• No, the person’s cells may not have everything they need, but his body can still exercise normally

• Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.

What would a doctor see in a person's blood who has diabetes?

• low oxygen

Which of these is part of your respiratory system?

• mouth

• nose

• stomach

• lungs

• mouth, nose, and lungs
