Descriptions Names[Advanced Search]

The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds. The aggregation, arrangement and bonding together of a set of components to form a protein complex. The aggregation, arrangement and bonding together of a set of components to form a photosystem I complex on the thylakoid membrane. The chemical reactions and pathways resulting in the formation of precursor metabolites, substances from which energy is derived, and any process involved in the liberation of energy from these substances. The light reactions of photosynthesis, which take place in photosystems II and I. Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH. NADPH generated from light reactions is used in sugar synthesis in dark reactions. Light reactions also generate a proton motive force across the thylakoid membrane, and the proton gradient is used to synthesize ATP. There are two chemical reactions involved in the light reactions: water oxidation in photosystem II, and NADP reduction in photosystem I. The aggregation, arrangement and bonding together of a set of components to form a protein complex, occurring at the level of an individual cell. The aggregation, arrangement and bonding together of a set of macromolecules to form a complex, carried out at the cellular level.
