WebSep 20, 2024 · Among organisms undertaking dark carbon fixation, we found that the reverse TCA cycle genes (aclA) were significantly more highly expressed in non-saline sediment (LDA score ≥2), and predominantly by Nitrospira (Fig. 6), which our results indicate also undertook complete ammonia oxidation (comammox) in this environment (Fig. 5). 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. images of the original statue of liberty
