    Water-splitting process: Electron transport and regulation. The first level (A) shows the original Kok model of the S-states cycling, the second level (B) shows the link between the electron transport (S-states advancement) and the relaxation process of the intermediate S-states ([YzSn], n=0,1,2,3) formation

  4. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The three steps involved are: [citation needed] Calvin cycle step 1 (black circles represent carbon atoms) Calvin cycle steps 2 and 3 combined. The enzyme RuBisCO catalyses the carboxylation of ribulose-1,5-bisphosphate, RuBP, a 5-carbon compound, by carbon dioxide (a total of 6 carbons) in a two-step reaction. [6]

  5. Photosystem I - Wikipedia

    en.wikipedia.org/wiki/Photosystem_I

    Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH. [2]

  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 ...

    en.wikipedia.org/wiki/Photosynthesis_System

    The photosynthetic rate (Rate of CO 2 exchange in the leaf chamber) is the difference in CO 2 concentration through chamber, adjusted for the molar flow of air per m 2 of leaf area, mol m −2 s −1. The change in H 2 O vapour pressure is water vapour pressure out of leaf chamber, in mbar, minus the water vapour pressure into leaf chamber, in ...
