Biophotonics of Photosynthesis

摘要: Biophotonics (an extension of photonics), in a broad sense, refers to techniques and phenomena related interaction between biological matter light (i.e., photons). For example, Nature uses biophotonics harvest photons achieve photosynthesis create vision. Light-absorbing pigments various systems initiate highly complex series photoinitiated processes. Photosynthesis is likely the best-known most widespread process involving entities. In photosynthesis, harvested its energy used drive chemical reactions that support nearly all life on Earth. Photosynthetic organisms possess large variety pigment–protein complexes (which perform as either lightharvesting antennae or reaction centers (RCs) where primary photochemistry takes place), containing dense networks chlorophylls (Chls) other pigments. plants, algae, cyanobacteria, these proteins are grouped into Photosystem I (PS I) II II) work together parts electron transfer chain [1, 2]. Other organisms, incapable oxygenic have dissimilar antenna arrangements, but, interestingly, RC design similar for known photosynthesizing species (see below). Detailed information structures photosynthetic was obtained by X-ray crystallography [3–10].
