In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. In summary, it takes six turns of the Calvin cycle to fix six ... how does radioactive dating work quizletWebSo this is it. This is the dark reaction. We were able to take the byproducts of the light reactions, the ATP and the NADHs-- there's some more ATP there-- and use it to fix carbon. This is called carbon fixation. When you take carbon in a gaseous form and you put it into a solid structure, that is called carbon fixation. photo picture image 違い
