Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?

• A Yes, her cells just need to combine amino acids to release energy.

• B No, her cells need to combine glucose into starch molecules to release energy.

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

• D Yes, her cells just need oxygen to release energy.
