6. Some students have the misconception that during cellular respiration, the matter in glucose is somehow turned into energy. Consider that when we exercise, we burn glucose and also lose mass. Why does this happen?
A) Our cells use up the potential energy stored in glucose, and losing that energy during exercise reduces our mass.
B) Our cells convert the mass in glucose into energy, which is weightless.
C) Our cells convert the mass in glucose into energy that is used during exercise. Losing that energy reduces our mass.
D) Our cells convert glucose into CO2 and water, which are eliminated from our bodies when we exercise.
