Glucose is broken down through cellular respiration, which involves a large number of chemical reactions. At the end of the cellular respiration process, a large number of ATP molecules are generated, but yet, not all of the possible energy that is contained in a molecule of glucose can be harnessed through these chemical reactions to generate ATP. In other words, during cellular respiration, not all of the energy that is contained in a molecule of glucose is converted into the energy stored in ATP. What happens to the remaining energy?
A. It is donated to molecules in the cellular respiration process to reduce them B. It is used to drive exergonic reactions C. It is lost as heat D. It is destroyed
