The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. The antenna pigments are predominantly chlorophyll b, xanthophylls, and carote… A light-harvesting complex consists of a number of chromophores which are complex subunit proteins that may be part of a larger super complex of a photosystem, the functional unit in photosynthesis. It is used by plants and photosynthetic bacteria to collect more of the incoming light than … See more Photosynthesis is a process where light is absorbed or harvested by pigment protein complexes which are able to turn sunlight into energy. Absorption of a photon by a molecule takes place when pigment protein complexes … See more Purple bacteria is a type of photosynthetic organism with a light harvesting complex consisting of two pigment protein complexes referred to as LH1 and LH2. Within the photosynthetic membrane, these two complexes differ in terms of their arrangement. … See more The antenna-shaped light harvesting complex of cyanobacteria, glaucocystophyta, and red algae is known as the phycobilisome which is composed of linear tetrapyrrole … See more • Caffarri (2009)Functional architecture of higher plantphotosystem II supercomplexes.

WebIn LH complexes of bacteria, BChl-a molecules are the main pigments involved in harvesting the solar light and in the excitation energy transfer processes. Especially … WebLight-harvesting complexes, excited by photons of light, are made of proteins and sugars. proteins, cofactors, and pigment. pigment and sugars. proteins and water. When electrons are passed through an electron transport chain, released energy is lost as heat. splits water into hydrogen and oxygen. fuses carbon dioxide molecules into a sugar. the klub 17: klub exile portal
