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. Adenosine triphosphate (ATP) is produced as the form of energy that can be used for other cellular processes.

Detailed explanation-3: -Glucose is the molecule normally used for respiration-it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules. Respiration is a series of chemical reactions, but this equation summarises the overall process.

Detailed explanation-4: -Explanation: Oxygen is neither a product nor reactant in glycolysis. Glycolysis is unique in that it takes place within the cytoplasm of the cell and does not require oxygen. It is an anaerobic reaction that produces pyruvate, NAD, and ATP.

Detailed explanation-5: -The first reactant in the equation for cellular respiration is oxygen.
