• Oxygen

• Molecules from both food and air

• amino acids

We need glucose from food to make energy. We can get glucose from starches and our body breaks it down. We can also get glucose straight from candy and syrup. What is the difference?

• A. Nothing would happen to her ability to exercise, but her digestive system would not work as hard since glucose is already broken down.

• With syrup or candy it would be harder to exercise because the digestive system would need more enzymes to combine glucose molecules together

• Nothing would happen to the ability to exercise, but the respiratory system would have to work harder since glucose has more energy than oxygen.

• It would be easier because glucose moves through the circulatory system faster than other food molecules

Should starch molecules ever be found in the cell?

• No, they are too big to get into the circulatory system and cells.

• Yes, they are needed in the cells to make energy.

• The cells put glucose back together to form starch molecules

How do molecules in the different parts of the body affect exercise?

• Only molecules in the small intestine matter

• Only molecules in the mouth and lungs matter

• Starch and glucose molecules should be high or normal in small intestines and oxygen should be high or normal in lungs.

• Starch and glucose and oxygen should be high or normal in lungs

How would the altitude (how far above and below) and what a team eat for dinner affect the team’s performance?

• The higher the altitude, the more oxygen there is and more energy can be made. Teams need both starch and protein for energy.

• The higher the altitude, the less oxygen there is and less energy can be made. Players should only eat starches that give glucose before a game.

• The higher the altitude, the less oxygen, and less energy. It does not matter what the team eats before the game.

• Only starches break down to glucose. Only glucose can make energy in cells. It does not matter what altitude they play in.

What is more important, molecules for food, or molecules from air to make the body work properly?

• Molecules from food.

• Molecules from air.

• Molecules from food and air are both equally important.

What molecules need to be broken down, and where does this happen?

• The small intestine breaks down starches and proteins and the respiratory system breaks down oxygen.

• The small intestine breaks down only starches.

• The small intestine breaks down only proteins

• A. The small intestine breaks down starches and proteins. Oxygen molecules do not need to be broken down because they are already small enough to fit into the cell.

If there is a problem with the respiratory system, how would this affect a person’s energy level?

• A person needs oxygen for cells to work properly. Low oxygen will result in low energy.

• If the respiratory system is not working properly, the digestive system will need to work harder to make more glucose.

• Oxygen molecules will not be broken down properly.

• Glucose will not get to the cells.
