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.

Where A is the net carbon assimilation rate; CE is the carboxylation efficiency, which was determined from the initial slope of the A/Ci response curve (Ci less than 200 mol mol); Ci is the leaf internal CO2 concentration; Amax is the maximum net carbon assimilation rate at saturating CO2; and Rd is the day respiration.
Moreover, these models help our understanding of carbon assimilation and water loss in vine canopies--two very important topics that are essential to understand if we are to deal successfully with pressures brought about by climate change and its inevitable effect on water availability.
Malate synthase, GLcB, initially was characterized as an important enzyme of the glyoxylate shunt involved in carbon assimilation as energy source to bacilli [6].
Reduction of root function and belowground carbon sink capacity due to flooding would lead to decreased net carbon assimilation rates.
Based on the results of the biochemical and carbon assimilation tests, the species of Acinetobacter identified were A.
This indicates that stomatal control of WUE predominates over that by carbon assimilation capacity among the rice genotypes examined in this study.
This further demonstrates the close and rapid link between carbon assimilation and rhizosphere respiration.
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.
Carbon assimilation through Crassulacean acid metabolism (CAM) is regarded as an adaptive trait for plant species native to high-light, water-limited habitats (Taiz and Zeiger 1991).
