  2. Fractionation of carbon isotopes in oxygenic photosynthesis

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

    The overall general equation for the light-independent reactions is the following: [11] 3 CO 2 + 9 ATP + 6 NADPH + 6 H + → C 3 H 6 O 3-phosphate + 9 ADP + 8 P i + 6 NADP + + 3 H 2 O. The 3-carbon products (C 3 H 6 O 3-phosphate) of the Calvin cycle are later converted to glucose or other carbohydrates such as starch, sucrose, and cellulose.

  3. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis and cellular respiration are distinct processes, as they take place through different sequences of chemical reactions and in different cellular compartments (cellular respiration in mitochondria). [15] [16] The general equation for photosynthesis as first proposed by Cornelis van Niel is: [17]

  4. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    2 O → glyceraldehyde-3-phosphate (G3P) + 6 NADP + + 9 ADP + 8 P i (P i = inorganic phosphate) Hexose (six-carbon) sugars are not products of the Calvin cycle. Although many texts list a product of photosynthesis as C 6 H 12 O 6, this is mainly for convenience to match the equation of aerobic respiration, where six-carbon sugars are oxidized ...

  5. Compensation point - Wikipedia

    en.wikipedia.org/wiki/Compensation_point

    The CO 2 compensation point (Γ) is the CO 2 concentration at which the rate of photosynthesis exactly matches the rate of respiration. There is a significant difference in Γ between C 3 plants and C 4 plants: on land, the typical value for Γ in a C 3 plant ranges from 40–100 μmol/mol, while in C 4 plants the values are lower at 3–10 μmol/mol. Plants with a weaker CCM, such as C2 ...

  6. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2 where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars , starches , cellulose , lignin , and so forth). The value of the photosynthetic efficiency is dependent on how light energy is defined – it depends on whether we count only the light that is absorbed, and on ...

    AMSTERDAM (Reuters) -The head of the chemical weapons watchdog said on Thursday he would ask Syria's new leaders to grant investigators access to the country to continue work identifying ...

  8. Oxygen evolution - Wikipedia

    en.wikipedia.org/wiki/Oxygen_evolution

    The half reaction, balanced with acid, is: 2 H + + 2e − → H 2. At the positively charged anode, an oxidation reaction occurs, generating oxygen gas and releasing electrons to the anode to complete the circuit: 2 H 2 OO 2 + 4 H + + 4e −. Combining either half reaction pair yields the same overall decomposition of water into oxygen and ...
