carbon fixation

The reduction of CO2 to organic compounds by living organisms—classically equated to photosynthesis, which requires sunlight and H2O as an electron donor, converting inorganic carbon (CO2) into organic compounds.


a chemical element, atomic number 6,atomic weight 12.011, symbol C. See Table 6.

asymmetric carbon atom
one bonded to four different atoms. See also isomer.
carbon fiber
made by the pyrolization of polymer fibers at very high temperatures and used in various forms as soft tissue implants, particularly in tendon and ligament repair.
carbon fixation

Initial observations show that the maximum carbon assimilation rates are greatest in the high nitrate group, followed by the medium and low nitrate groups ([A.
A robot arm scooped soil samples into the device, which tested metabolism of possible Martian organisms, carbon assimilation, and gas changes in the soil.
These results provided evidence pointing towards the role of carbon accumulation in cell walls, by ensuring a continuous carbon fixation to the cellulose and hemicellulose, the fixed structural components of bamboo cell walls, which in turn facilitated the rapid carbon assimilation in the source by contributing to the biomass accumulation.
