Doctors tested a patient to find out what molecules were in his cells. His cells contained normal levels of glucose molecules and amino acid molecules, and low levels of oxygen molecules. Will this patient be able to exercise normally?
Yes, his body is working properly enough to exercise.
No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.
No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
No, his respiratory system is not working because he is not breathing correctly.
