2. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .

3. 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:

4. Biogeochemical cycle - Wikipedia

   en.wikipedia.org/wiki/Biogeochemical_cycle

   Additionally, carbon is stored in fossil fuels and is released into the atmosphere through human activities such as burning fossil fuels. In the nitrogen cycle, atmospheric nitrogen gas is converted by plants into usable forms such as ammonia and nitrates through the process of nitrogen fixation.

5. C4 carbon fixation - Wikipedia

   en.wikipedia.org/wiki/C4_carbon_fixation

   The main carboxylating enzyme in C 3 photosynthesis is called RuBisCO, which catalyses two distinct reactions using either CO 2 (carboxylation) or oxygen (oxygenation) as a substrate. RuBisCO oxygenation gives rise to phosphoglycolate , which is toxic and requires the expenditure of energy to recycle through photorespiration .

6. Evolution of photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Evolution_of_photosynthesis

   There are three major metabolic pathways by which photosynthesis is carried out: C 3 photosynthesis, C 4 photosynthesis, and CAM photosynthesis. C 3 photosynthesis is the oldest and most common form. A C3 plant uses the Calvin cycle for the initial steps that incorporate CO 2 into organic material.

7. Fractionation of carbon isotopes in oxygenic photosynthesis

   en.wikipedia.org/wiki/Fractionation_of_carbon...

   The chemical pathway of oxygenic photosynthesis fixes carbon in two stages: the light-dependent reactions and the light-independent reactions.. The light-dependent reactions capture light energy to transfer electrons from water and convert NADP +, ADP, and inorganic phosphate into the energy-storage molecules NADPH and ATP.

9. Biological carbon fixation - Wikipedia

   en.wikipedia.org/wiki/Biological_carbon_fixation

   Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.
