DENDROLOGY

Detailed explanation-1: -Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Detailed explanation-2: -During cellular respiration, the reactants-glucose (sugar) and oxygen-combine together to form new products: carbon dioxide molecules and water molecules.

Detailed explanation-3: -Glucose is a 6-carbon structure with the chemical formula C6H12O6. It is a ubiquitous source of energy for every organism in the world and is essential to fuel both aerobic and anaerobic cellular respiration.

Detailed explanation-4: -Moreover, photosynthesis reactants CO2 and H2O are products of cellular respiration. And the reactants of respiration, C6H12O6 and O2, are the products of photosynthesis.
