摘要: Publisher Summary This chapter describes the structure and function of light-harvesting pigment-protein complexes. The antenna complexes photosynthetic organisms are multi-molecular energy transport systems whose is to funnel excited-state photochemical reaction center (RC). These special pair RC thus form a cooperative, highly regulated transfer trapping system. system starting point for light-induced redox leading ultimately production adenosine triphosphate (ATP) generation reducing power. Light-harvesting antennae various composed generally number (antenna) varying absorption maxima. Such heterogeneous directed RC. structures acting within same can differ greatly. Pigment molecules (Chl, BChl, bilins, carotenoids) ordered complexes, their position orientation follow defined laws symmetry. is, therefore, very efficient, flows with little dissipation Antennae contain large pigment molecules, approximately 25–1000 pigments per
