True/ False. The primary molecules in the respiratory system are oxygen and carbon dioxide molecules.

• True

• False

1. Glucose (orange circles)  starts in the digestive system. According to Figure 2, where does it move next in order to travel to the cells.

• 1. Circulatory system

• Digestive system

• 1. Respiratory system

• 1. Lymphatic system

1. Using Figure 3, what two molecules do your cells need to function correctly and allow a person to have energy to exercise?

• Glucose

• 1. Fiber

• 1. Oxygen

• Protein

How can the program’s doctors make sure the astronauts' bodies work well enough to exercise in space?

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

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

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

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

Stella

1. On Day 1, doctors tested Stella 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 Stella be able to exercise normally?

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

• 1. 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.

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

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

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

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

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

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

Jamal

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

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

• 1. No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.

• 1. 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 from the body to function.

1. 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 continued normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired?

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

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

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

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