In the process of respiration,
During respiration, glucose is converted into carbon dioxide and water in the presence of oxygen within a living cell. The energy is released in the form of ATP or adenosine triphosphate. So, we can say that the energy stored in glucose is transferred into ATP. This process can be shown in the form of a word equation as shown below:
Glucose + oxygen ----> carbon dioxide + water + energy
So, the correct answer is option C.
