Also, cellular respiration is c6h12o6 + o2 -> h2o + co2 and energy and photosynthesis is backwards of photosynthesis. It’s light energy + co2 + water to make c6h12o6 and o2. So the reactants in cellular respiration are the products in photosynthesis and the products in cellular respiration are the reactants of photosynthesis
