It is composed of a core complex responsible for charge separation and the first steps of electron transport and a peripheral antenna system, which are involved in light harvesting and transfer of excitation energy to the reaction centre (Jensen et Light emission at 715-720 nm upon excitation at 440 and 475 nm, and subsequent transfer of excitation energy to the photosystem I core with a relative slow rate of 25 ns(-1). 1 Publication Manual assertion based on experiment in i Fotosystém je označení pro velký proteinový komplex (reakční centrum) účastnící se fotosyntézy a nacházející se na membráně tylakoidů rostlin, řas a mnohých fotosyntetizujících bakterií či sinic.

The core complex, which contains the reaction center, contains seven polypeptides. Photosystem I is located on the outer surface of the thylakoid membrane and is bind to the special reaction center known as P700, whereas PS II is located on the inner surface of the thylakoid membrane and the reaction center is known as P680.

The first initial step of trapping solar energy and the then conversion by light-driven electron transport. Abstract Photosystem I is the light-driven plastocyanin-ferredoxin oxidoreductase in the thylakoid membranes of cyanobacteria and chloroplasts. In recent years, sophisticated spectroscopy, molecular genetics, and biochemistry have been used to understand the light conversion and electron transport functions of photosystem I. Photosystem I is a trimeric complex that forms a large disk.
