Answer:
The correct answer is option energy is a product.
Explanation:
Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.
All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.  
1. Glycolysis produces- 2 ATP, 2 NADH,  
2. Oxidative carboxylation produces- 2 NADH,  
3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and  
4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.
Thus, option energy is a product is a correct option.
