WebHow does carbon fixation occur? Carbon fixation is the process by which inorganic carbon is added to an organic molecule. Carbon fixation occurs during the light independent reaction of photosynthesis and is the first step in the C3 or Calvin Cycle. What is carbon fixation used for? 1 Carbon Fixation. WebDec 24, 2024 · In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO 2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.
