No, the reactants of cellular respiration are not the same as the reactants of photosynthesis. In cellular respiration, the reactants are glucose and oxygen, which are converted into carbon dioxide, water, and energy (in the form of ATP). On the other hand, the reactants of photosynthesis are carbon dioxide, water, and sunlight, which are converted into glucose and oxygen. Cellular respiration and photosynthesis are complementary processes that occur in different cellular organelles and have opposite chemical reactions.
