A student thinks that the human body only works properly when cells are getting molecules from food and molecules from air. Is the student correct?

• Yes, the body only works when cells get molecules from food and molecules from air.

• No, the body only works when cells are getting molecules from different types of food.

• No, the body only works when the lungs get molecules from air, and the stomach gets molecules from food.

• No, the body works as long as cells are making all the molecules they need.

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.

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.
