Core Difference Between Photosystem I and Photosystem II. Photosystem I has pigment system 1 while photosystem II has pigment system 2; PS1 is located on the outer surface of the thylakoid membrane while PS2 in the grana of the thylakoid membrane

Photosystem I (n.). 1. A large multisubunit protein complex that is found in the THYLAKOID MEMBRANEIt uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to drive electron transfer reactions that result in either the reduction of NADP to NADPH …

Electron Replacement 2006-02-01 · The carotenoids fulfill a triple function in photosystem I. First, they prevent the system from damage by over-excitation caused by excess light. In addition, they perform a structural role and function as additional antenna pigments . 2010-06-15 · 1. Biochemistry. 2010 Jun 15;49(23):4740-51. doi: 10.1021/bi901807p.

The photosystem I proteins are responsible for the precise arrangement of cofactors and determine redox properties of the electron transfer centers. With the availability of genomic information and the structure of photosystem I, one can now probe the functions of photosystem I proteins and cofactors. Photosystem I (PS I) is a chlorophyll (Chl)–protein complex that functions as a light-driven plastocyanin:ferredoxin oxidoreductase. Electron transfer from plastocyanin ( E m ≈ +370 mV) to ferredoxin ( E m ≈ −430 mV) would normally be very endergonic (Δ G ≈ +87 kJ/mol), but is rendered favorable by coupling to absorption of a photon of visible light.

Photosystem I is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. 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. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH. The combined action of the entire photosynthetic electron transport chain also produces a p

Ascorbate in thylakoid lumen functions as an alternative electron donor to photosystem II and photosystem I. J Mano, É Hideg, K Asada.

The PsbP domain protein 1 (PPD1; At4g15510) is located in the thylakoid lumen of plant chloroplasts and is essential for photoautotrophy, functioning as a PS I assembly factor. Photosystem I is the light-driven plastocyanin-ferredoxin oxidoreductase in the thylakoid membranes of cyanobacteria and chloroplasts.
