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.

What does the circulatory system do?

• Stores glucose for use at a later time.

• Breaks down starch.

• Breaks down protein.

• Carry the molecules to the cells and other body systems.

Which molecules don't need to be broken down?

• starch

• oxygen

• protein

• amino acids

What can happen if your cells don't get the molecules they need to function properly?

• They will need more of the other molecules to make up for the missing ones.

• They will be fine.

• They will start to shut down.

• They can survive as long as they have enough water.

Jaxson was tested to find out what molecules was inside his cells. His cells contained normal levels of oxygen, low levels of amino acid molecules, and low levels of glucose. Will Jaxson be able to exercise normally?

• Yes, as long as his cells have enough oxygen, he can exercise.

• No, his cells need glucose to react with oxygen to release enough energy to exercise.

• No, his cells need more amino acid molecules.

• No, his cells need glucose to react with amino acids.
