WebThe basic chemical reaction for oxygenic photosynthesis is: CO 2 + 2H 2 O + photons → [CH 2 O] + O 2 + H 2 O. During photosynthesis, one molecule of carbon dioxide and 2 molecules of water are converted into molecular oxygen and some carbohydrate. Creating organic compounds from inorganic carbon is known more generally as “carbon fixation.”.
