Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is the second photosystem in the photosynthetic light reactions of algae, plants, and some bacteria. Photosystem I is an integral membrane protein complex that uses light energy to produce the high energy carriers ATP and NADPH. Similar to all terrestrial and chlorophyll-possessing plants, atmospheric CO 2 is the primary source of carbon required for photosynthesis- the reason for higher cell densities and increased metabolism rate. Photosynthesis. photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.. 1.
