Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis.

ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.
