  2. Photorespiration - Wikipedia

    en.wikipedia.org/wiki/Photorespiration

    Photorespiration may be necessary for the assimilation of nitrate from soil. Thus, a lowering in photorespiration by genetic engineering or because of increasing atmospheric carbon dioxide may not benefit plants as has been proposed. [13] Several physiological processes may be responsible for linking photorespiration and nitrogen assimilation.

  3. C3 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C3_carbon_fixation

    C3 carbon fixation is prone to photorespiration (PR) during dehydration, accumulating toxic glycolate products. In the 2000s scientists used computer simulation combined with an optimization algorithm to figure out what parts of the metabolic pathway may be tuned to improve photosynthesis.

  4. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    One efficiency-focused research topic is improving the efficiency of photorespiration. Around 25% of the time RuBisCO incorrectly collects oxygen molecules instead of CO 2, creating CO 2 and ammonia that disrupt the photosynthesis process. Plants remove these byproducts via photorespiration, requiring energy and nutrients that would otherwise ...

  5. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    2 in photorespiration. The rate of photorespiration is higher at high temperatures. Photorespiration turns RuBP into 3-PGA and 2-phosphoglycolate, a 2-carbon molecule that can be converted via glycolate and glyoxalate to glycine. Via the glycine cleavage system and tetrahydrofolate, two glycines are converted into serine plus CO 2. Serine can ...

  6. 2-Phosphoglycolate - Wikipedia

    en.wikipedia.org/wiki/2-Phosphoglycolate

    Therefore, degradation of 2-PG during photorespiration is important for cellular homeostasis. Photorespiration is the main way of chloroplasts to rid themselves of 2-PG. [ 4 ] However, this pathway comes at a decreased return on investment ratio as 2-PG is transformed to 3-phosphoglycerate in an elaborate salvage pathway at the cost of one ...

  8. Fractionation of carbon isotopes in oxygenic photosynthesis

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

    Carbon on Earth naturally occurs in two stable isotopes, with 98.9% in the form of 12 C and 1.1% in 13 C. [1] [8] The ratio between these isotopes varies in biological organisms due to metabolic processes that selectively use one carbon isotope over the other, or "fractionate" carbon through kinetic or thermodynamic effects. [1]
