  2. C4 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C4_carbon_fixation

    C 4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960s discovery by Marshall Davidson Hatch and Charles Roger Slack. [1] C 4 fixation is an addition to the ancestral and more common C 3 carbon fixation.

  3. Crassulacean acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Crassulacean_acid_metabolism

    The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.

  4. C3 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C3_carbon_fixation

    Calvin–Benson cycle. C 3 carbon fixation is the most common of three metabolic pathways for carbon fixation in photosynthesis, the other two being C 4 and CAM.This process converts carbon dioxide and ribulose bisphosphate (RuBP, a 5-carbon sugar) into two molecules of 3-phosphoglycerate through the following reaction:

  5. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...

  6. Evolution of photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_photosynthesis

    [citation needed] [26] In C 4 photosynthesis, carbon is fixed by an enzyme called PEP carboxylase, which, like all enzymes involved in C 4 photosynthesis, originated from non-photosynthetic ancestral enzymes. [27] [28] A second mechanism, CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid ...

  7. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    The term photosynthesis is derived from the Greek phōs (φῶς, gleam) and sýnthesis (σύνθεσις, arranging together), [96] [97] [98] while another word that he designated was photosyntax, from sýntaxis (σύνταξις, configuration). Over time, the term photosynthesis came into common usage. Later discovery of anoxygenic ...

  9. RuBisCO - Wikipedia

    en.wikipedia.org/wiki/RuBisCo

    RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere.While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared to that catalyzed by RuBisCO.
