Detailed explanation-1: -Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
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: -The Reactants 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-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. Respiration is a series of chemical reactions, but this equation summarises the overall process.
Detailed explanation-5: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
