Metabolism Test

What should doctor's look at to make sure a person's body is well enough to exercise?

• The body can make enough energy by getting enough sleep
• the cells are getting different types of molecules from food
• the cells are getting the molecules they need from food and air
• the stomach is getting molecules it needs from food and air

Starburst jellybeans are almost entirely made up of glucose molecules. If a person ate nothing but Starburst jellybeans for two weeks, what would happen to her ability to exercise?

• Her digestive system wouldn't work as hard, since glucose is already small enough to get to her cells but nothing would happen to her ability to exercise.
• The glucose molecules move through the circulatory system faster than other food molecules so it will be easier to exercise
• Her respiratory system wouldn't work as hard since glucose has more energy than oxygen so nothing would happen to her ability to exercise
• The digestive system would need to use more enzymes to combine the glucose molecules together so it would be harder to exercise

A star runner went to the doctor for some testing and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this runner be able to exercise normally?

• yes, the glucose and oxygen molecules can react together to release energy for the body to function
• no, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose
• yes, as long as his cells have glucose, they don't need anything else to release energy for the body to function
• no, his body systems are working, but he needs to eat different food; in cells, only amino acids react with oxygen to release energy

Gastroparesis is a problem with the digestive system that makes it difficult to digest food. Why would it be harder to exercise when you have a digestion problem?

• you would need to breathe in a lot more air because your body would have fewer molecules from food
• your cells would have molecules from air, but would not get enough molecules from food
• you would not be able to sleep, which would make you too tired to exercise
• you wouldn't get any of the molecules your cells need to exercise

Two friends facetimed each other during their workouts. Kristina lives in Colorado, which is a high altitude, Jennifer lives in Louisiana, which is slightly below sea level. Both friends ate some corn for lunch before working out but the friend in Colorado also ate some fish with her lunch. Which friend do you think had a better workout?

• Kristina probably did better because her cells released energy from breaking down the protein in her digestive system, which then combined with oxygen in the cells
• Both did equally well because glucose from starch can react with oxygen or proteins to release energy
• Jennifer probably did better because her cells released energy from oxygen reacting with glucose, which was broken down from the starch in her digestive system
• Both did equally well because their digestive systems just need to break down starch into glucose for cells to release energy

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?

• No, the body only works when cells are getting molecules from different types of food
• Yes, the body only works when cells get molecules from food and air
• No, the body works as long as cells are making all the molecules they need.
• No, the body only works when the lunges get molecules from air, and the stomach gets molecules from food

Drake's respiratory system is not working well. Why would this affect his ability to exercise?

• His cells will not work well when they have low levels of oxygen
• His cells will not work because molecules from air will be too large for her body to use
• His respiratory system will not be able to break down molecules from air into oxygen
• His digestive system will have to work twice as hard to get the same amount of energy from glucose molecules

Brock's cells contain normal levels of oxygen molecules, low levels of amino acids, and low levels of glucose molecules. Will Brock be able to exercise normally?

• No, his cells need glucose to react with oxygen to release enough energy to exercise
• No, his cells need amino acids to react with oxygen to release enough energy to exercise
• No, his cells need glucose to react with amino acids to release enough energy to exercise
• Yes, as long as his cells have enough oxygen, his body will be able to exercise

Asthma is a condition in which it can very hard for a person to breathe in enough air. Would it also be difficult for someone with asthma to exercise?

• Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.
• No, as long as the person's cells are getting different types of molecules from food, he can still exercise
• No, the person's cells may not have everything they need, but his body can still exercise normally
• No, as long as the person is getting enough sleep, he will make enough energy to exercise

Jackson has been feeling tired a lot, so his doctors ran some tests. The tests show that Jackson's cell contain normal levels of oxygen and low levels of glucose. Does this explain why Jackson has been feeling tired?

• Yes, Jackson's respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells
• Yes, Jackson's respiratory system is working, but his digestive system is not turning the oxygen into glucose
• Yes, Jackson'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 Jackson because his cells have all the molecules they need.
