Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Photosynthesis uses light energy to make ATP from carbon dioxide and water while cellular respiration makes carbon dioxide while using glucose to make ATP.The CO2 is used by the plants while animals make CO2.hotosynthesis and cellular respiration are said to be reverse chemical processes because the reactants of photosynthesis are the products of cell respiration and the reactant â¦ s of cell respiration are the products of photosynthesis.
