Photosynthesis produces the glucose that is utilized in cellular respiration to make ATP. The glucose is then transformed back into carbon dioxide, which is used in photosynthesis. While water is split down to form oxygen through photosynthesis, in cellular respiration oxygen is mixed with hydrogen to form water.The oxygen production compares to the rate of photosynthesis because there is a greater flow of oxygen when it narrates to photosynthesis at a great rate.
The overall reaction is described as follows.
H₂O + CO₂ → C₆H₁₂O₆ + O₂
