Credits: 10. 0 0. Rep: 3 years ago. Photosynthesis: Reactants Water, Light, Carbon Dioxide. Cellular Respiration: Reactants Oxygen, Sugars. Products Carbon Dioxide, Water, Light. Photosynthesis' reactants and products are just the switched version of cellular respiration, and vice versa.By 'light' for cellular respiration, I'm assuming it just means energy.redits: 10. 0 0.
