Detailed explanation-1: -Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.
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: -The glucose used to produce ATP during cellular respiration is derived from dietary sources and glycogen, a storage form of glucose found in the human body.
Detailed explanation-4: -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.
Detailed explanation-5: -Cellular respiration is the process by which food, in the form of sugar (glucose), is transformed into energy within cells.
