Answer:
The correct answer is "glucose".
Explanation:
Cellular respiration is the pathway of chemical reactions at which glucose is broken down to produce energy. In cellular respiration oxygen is used to broke down glucose, resulting in the production of carbon dioxide and water as by-products. The final objective of cellular respiration is to produce energy in the form of adenosine triphosphate (ATP). Therefore, the biomolecule that is typically used as source of energy for cellular respiration is glucose, and ATP is the molecule used to carry energy.
