Please help me it’s 15 points!
DedPeter [7]

Answer:

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

Explanation:

During exercise, the muscles actually need additional energy. Such energy is derived from the reaction of oxygen and glucose. Breathing rate increases in order to take in more oxygen and remove the carbon dioxide that is produced. At this point, the heart rate also increases in order to supply the muscles with extra oxygen.

Such exercises that are aerobic require oxygen to react with glucose in order for energy (ATP) to released which is needed during the exercise.
