Photosynthesis Breakthrough May Lead To New Energy Sources

Plants and algae, as well as cyanobacteria, use photosynthesis to produce oxygen and "fuels," the latter being oxidizable substances like carbohydrates and hydrogen. There are two pigment-protein complexes that orchestrate the primary reactions of light in oxygenic photosynthesis: photosystem I (PSI) and photosystem II (PSII). Researchers writing in PNAS say they have taken a significant step closer to understanding how these photosystems work their magic, which may boost the effort to develope new sources of energy. read more
