Detailed explanation-1: -Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes.

Detailed explanation-2: -Where is oxygen used in cellular respiration? In cellular respiration, oxygen is used in the inner mitochondrial membrane in the electron transport chain to facilitate oxidative phosphorylation.

Detailed explanation-3: -During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

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 oxygen that is used in cellular respiration primarily comes from the atmosphere. In cellular respiration, oxygen is used as the terminal electron acceptor of the mitochondrial electron transport chain.
