Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem II 20. Photosystem is the form of pigments on the thylakoid membrane1. A photosystem has a similar collection of pigment molecules that focus the energy to a reaction center where the electrons are ejected from the molecule. In photosystem I, the electron comes from the chloroplast electron transport chain. This term is something of a misnomer, for these reactions can take place in either light or darkness.

Calvin Cycle – Products / Outputs 29. Because light energy powers this reaction in the chloroplasts, the production of ATP during photosynthesis is referred to as photophosphorylation, as opposed to oxidative phosphorylation in the electron-transport chain in the mitochondrion . Water (H20) Reactant of Photosystem II. Photosynthesis is a complex process which involves two reactions called light-dependent reactions wherein a green pigment called chlorophyll is used to convert light energy into chemical energy. It collects energy over the wavelengths and concentrates it to one molecule which uses the energy to pass one of its electrons on to a series of enzymes1. Molecules called pigments absorb energy from light.The main pigment in photosynthesis is called chlorophyll.
