The test report above shows the level of molecules in different parts of the patient's body. How would you expect this patient to do on an exercise test?
Well; his body is working properly.
Poorly; his digestive system is not combining glucose molecules together for the cells to use
Poorly; his digestive system is not breaking down molecules from food into glucose.
Poorly; his respiratory system is not breaking down oxygen molecules into glucose.
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.
