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. The light-harvesting complexes and internal antenna of photosystem I absorb

Photosystem I, a membrane protein complex found in all oxygenic photosynthetic organisms, uses light energy to transfer electrons from plastocyanin to ferredoxin. Light energy captured by antenna chlorophylls is transferred rapidly to the primary electron donor, P 700. Function i Possible role could be the docking of the LHC I antenna complex to the core complex.

Photosystem. Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. From:Postharvest Physiology and Biochemistry of Fruits and Vegetables, 2019. Das Photosystem I (PS I) ist ein Proteinkomplex aus mehreren Membranproteinen, der im Zuge der Photosynthese eine Oxidation von Plastocyanin und die Reduktion von Ferredoxin durch absorbierte Photonen katalysiert.
