Function

[LHB_BLAVI] Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers. [RCEH_BLAVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [CYCR_BLAVI] The reaction center of purple bacteria contains a tightly bound cytochrome molecule which re-reduces the photo oxidized primary electron donor.^[1] [RCEM_BLAVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [LHG_BLAVI] One of the components of the bacteriochlorophyll-protein complex in the chromatophore membrane. [RCEL_BLAVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [LHA_BLAVI] Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
