Front

Can an athlete exercise as long as she eats different types of food?

Back

No, all cells need molecules from food and molecules from air to work properly.

Why is it a problem for Marisol's ability to exercise if her digestive system is not breaking down food molecules?

Back

Her cells will not work well because molecules from her food are not being broken down small enough to get to her cells.

Will a patient with normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules be able to exercise normally?

Back

No, her cells need glucose to react with oxygen to release energy.

What could prevent a person breathing normally from exercising normally? Options: not getting enough sunlight, not getting enough sleep, not eating enough food, nothing.

Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul’s cells contained glucose molecules, but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?

Back

Yes, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.

Front

Will a patient with normal glucose and amino acid levels but low oxygen levels be able to exercise normally?

Back

No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.

What could happen if Rico's breathing gear broke during a dive and he could not breathe as much air as usual?

Back

It would be difficult to swim, because his cells cannot work without molecules from air.
