摘要: In the light, photosynthetic cells can potentially suffer from oxidative damage derived reactive oxygen species. Nevertheless, a variety of oxygenic photoautotrophs, including cyanobacteria, algae, and plants, manage their systems successfully. present article, we review previous research on how these photoautotrophs safely utilize light energy for photosynthesis without photo-oxidative to photosystem I (PSI). The reaction center chlorophyll PSI, P700, is kept in an oxidized state response excess under high low CO2 conditions, tune utilization dissipate photo-excitation PSI. Oxidation P700 co-operatively regulated by number molecular mechanisms both electron donor acceptor sides strategies keep are diverse among which evolutionarily optimized ecological niche.
