- Two main subunits of PSI, PsaA and PsaB, are closely related proteins involved in the binding of the vital electron transfer cofactors P700, Acc, A0, A1, and Fx. (wikipedia.org)
- A0 accepts electrons from P700*, passes it to A1 of the same side, which then passes the electron to the quinone on the same side. (wikipedia.org)
- Ferredoxin (Fd) is a soluble protein that facilitates reduction of NADP+ to NADPH. (wikipedia.org)
- A laser ablation ICP-MS based method for multiplexed immunoblot analysis: applications to manganese-dependent protein dynamics of photosystem II in barley ( Hordeum vulgare L. (ku.dk)
- Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. (wikipedia.org)
- In addition, hydrocarbons produced by algae represent a potential means to store and sequester carbon [ 2 ]. (biomedcentral.com)
- This photosystem is known as PSI because it was discovered before Photosystem II, although future experiments showed that Photosystem II is actually the first enzyme of the photosynthetic electron transport chain. (wikipedia.org)
- Louis Duysens first proposed the concepts of Photosystems I and II in 1960, and, in the same year, a proposal by Fay Bendall and Robert Hill assembled earlier discoveries into a coherent theory of serial photosynthetic reactions. (wikipedia.org)
- In addition, kinetic limitations, such as the coupling of proton to electron transfer during plastoquinone reduction and oxidation and the slow rates of CO 2 fixation by Rubisco reduce photosynthetic efficiency. (biomedcentral.com)
- Ferredoxin (Fd) is a soluble protein that facilitates reduction of NADP+ to NADPH. (wikipedia.org)
- Furthermore, microalgae have enhanced environmental sustainability characteristics since they can utilize inorganic carbon (bicarbonate) sequestered in ponds that can be captured from CO 2 production point sources (power plants), unlike terrestrial plants. (biomedcentral.com)
- Compared to crop plants, microalgae have 2-10 times the biomass yield potential. (biomedcentral.com)
- Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. (wikipedia.org)
- Ultimately, the electrons that are transferred by Photosystem I are used to produce the moderate-energy hydrogen carrier NADPH. (wikipedia.org)
- The photon energy absorbed by Photosystem I also produces a proton-motive force that is used to generate ATP. (wikipedia.org)
