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
see dark reaction.

The parts of metabolism that guide carbon fixation through its unstable intermediate stages fall into the latter category, requiring help.
Both photosynthesis level and carbon fixation ability are affected by morphological characteristics, which are determined by both genetic and environmental factors (Parry et al.
In conclusion, this is a simple, inexpensive way to involve students in learning the biochemistry of carbon fixation in plants.
Recently, Dr Tim Schmidt joined CSIRO to pursue the computational modelling of rubisco, a key photosynthetic enzyme for carbon fixation, along with Collings and Dr Peter Vohralik.
The Energy Policy Act of 1992 directed the Energy Information Administration (EIA) to establish a mechanism for the voluntary collection of information on reductions in greenhouse gas emissions and carbon fixation.
The duration and magnitude of phytoplankton primary productivity impacts carbon fixation, carbon export, and air-sea carbon flux, so this work results in more accurate estimates of the oceanic net carbon biological uptake.
Cereal grains with C3 metabolism, including rice, wheat, barley, oats, and rye, show yield increases ranging from 25 to 64 percent, resulting from a rise in carbon fixation and reduction in photo-respiration.
NASDAQ: MBLX), an innovation-driven bioscience company focused on delivering sustainable solutions for plastics, chemicals and energy, today announced that it has received a subaward under the Advanced Research Projects Agency - Energy (ARPA-E) to work with the UCLA Henry Samueli School of Engineering and Applied Science to redesign carbon fixation pathways to increase the efficiency of capturing energy from sunlight.
Implementation of this technique, however, requires that the electron transfer rates (ETRs) measured by FRR fluorometry can be easily converted to carbon fixation rates via the electron requirement for carbon fixation (ER).
The objectives of this experiment were to (1) determine carbon storage and its spatial distribution in the ecosystems of the three forest stands with the same tree ages in the same region and (2) compare carbon fixation abilities in the ecosystem of the three forest stands.
The results showed that it is missing the entire set of genes needed for photosystem II and carbon fixation, essential parts of the molecular machinery that carries out photosynthesis in plants and cyanobacteria.
It involves an entirely new metabolic loop in the process of carbon fixation that turns chemical energy into simple sugars, and its evolution required major anatomical changes.
