Detailed explanation-1: -Oxygen and glucose are both reactants of cellular respiration. When one molecule of glucose is broken down, it can be converted to a net total of 36 or 38 molecules of ATP. This only occurs in the presence of oxygen.
Detailed explanation-2: -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-3: -The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis. Cellular respiration occurs in plant and animal cells. Plants use sunlight during photosynthesis to convert energy from the sun in order to manufacture sugar and the chemical energy ATP and to release oxygen.
Detailed explanation-4: -Aerobic respiration uses oxygen and glucose as reactants and makes ATP, carbon dioxide and water as products.
Detailed explanation-5: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.
