Term Information [More information on photosynthesis, light reaction]

Accession
GO:0019684
Name
photosynthesis, light reaction
Ontology
biological_process
Synonyms
photolysis
Definition
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. Source: http://www.arabidopsis.org
