WebAbstract. Carbon fixation is the process by which organic molecules are formed from inorganic carbon. This reaction requires CO2 to move from the atmosphere to the site of carbon fixation in the chloroplasts of plant cells, where it is used to produce sugars using the end products of light dependent photosynthetic electron transport (ATP and ...
