Membrane-inlet mass spectrometry reveals a high driving

Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. 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 . 2009-03-13 · Historically photosystem I was named "I" since it was discovered before photosystem II, but this does not represent the order of the electron flow. When photosystem II absorbs light, electrons in the reaction-center chlorophyll are excited to a higher energy level and are trapped by the primary electron acceptors.

Photosystems are membrane protein complexes which utilize light accept electrons while type II photosystems use quinones Overview. Like Photosystem II (PS II), Photosystem I (PS I) captures photons and transports them through chlorophyll molecules into a reaction center. In PS I 24 Oct 2014 Light energy is converted to chemical energy during photosynthesis.

Electron Replacement 2006-02-01 As in Photosystem II, light is harvested by antenna complexes, and the primary light reaction is a charge separation beginning stabilized by transfer of an electron to a quinone, but in Photosystem I the terminal electron acceptor is an FeS cluster, which permits reduction of ferredoxin.
