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.

Which molecules does your body's cells need to stay healthy?

• Starch/Glucse

• Protein/Amino Acid

• Oxygen

• All of the above

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.

In a patient with diabetes, how does their condition effect their body systems?

• Their glucose molecules get stuck in their respiratory system

• Their starch molecules get stuck in their digestive system

• Their glucose molecules get stuck in their circulatory system

• Their glucose molecules get stuck in their cells

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.

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.

The model has arrows pointing that say

- The same amount of oxygen in the mouth/throat

- Less oxygen in the lungs

- Less oxygen in the circulatory system

What condition does this model represent?

• Diabetes

• Asthma

• Healthy patient

Diagnose this patient:

Glucose Molecules in Cell: 15

Amino Acid Molecules in Cell: 50

Oxygen Molecules in cell: 250

• Diabetes

• Asthma

• Healthy

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.

-What does she need from the food she ate and the air she breathes so that she can go on her run?

-How do Rosa’s body systems work together to get the molecules she needs into her cells? ?

Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not be getting enough oxygen or glucose.

- Which body systems should the doctor test in order to find out whether Guillermo’s cells are getting enough oxygen and glucose and why?
