glucose and water

carbon dioxide and water

lactic acid and energy

Detailed explanation-1: -Aerobic respiration uses oxygen and glucose as reactants and makes ATP, carbon dioxide and water as products.
Detailed explanation-2: -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-3: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
Detailed explanation-4: -In aerobic respiration, oxygen is required to react with glucose to produce carbon dioxide, water, and energy in the form of ATP. In anaerobic respiration, glucose can be broken down into lactic acid to produce ATP.
