WebSo 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.
