Light-harvesting complex - Wikipedia
A light-harvesting complex consists of a number of chromophores [1] 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 would be captured by the photosynthetic reaction ...
Light-harvesting complexes of green plants - Wikipedia
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.
Photosynthetic Light-Harvesting (Antenna) Complexes…
We propose a simple, tentative explanation of the trimer issue, based on the 2D world created by photosynthetic membrane systems. Keywords: bacteriochlorophylls, chlorophylls, carotenoids, excitation energy transfer, light-harvesting complexes, photosynthesis, pigment-protein complexes, photosystems, photoprotection. 1. Introduction.
Light-Harvesting Complex - an overview | ScienceDirect Topics
Light-harvesting complex (LHC) proteins are a protein superfamily that bind chlorophylls (Chls) and carotenoids to facilitate the absorption of light energy and the transfer of excitation energy to the reaction centers of photosystems I (PSI) and II (PSII).
From light-harvesting to photoprotection: structural basis of …
2015年10月23日 · Light-Harvesting Complexes (LHCs) are pigment-protein systems responsible for photon absorption and transfer of the excitation energy to the reaction center, where charge separation occurs 2. All...
Principles of light harvesting from single photosynthetic complexes
Here, we discuss the following three key principles of this flow and of photosynthetic light harvesting: thermal fluctuations of the protein structure; intrinsic conformational switches with defined functional consequences; and environmentally triggered conformational switches.
Structural analysis and comparison of light-harvesting complexes …
2020年4月1日 · In vascular plants, the most abundant antenna complex is the major light-harvesting complex LHCII, which contains three apoproteins (Lhcb1, Lhcb2, and Lhcb3) that form Lhcb1/Lhcb2/Lhcb3 heterotrimers in vivo with variable stoichiometries [13], or homotrimers of Lhcb1 or Lhcb2 in vitro [14, 15].
What is the light-harvesting complex? - CK-12 Foundation
The light-harvesting complex, also known as antenna complex, is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
Structure, Organization and Function of Light-Harvesting Complexes ...
2021年9月10日 · To expand the light-harvesting cross sections and enlarge the range of spectral regions useful for photosynthesis, photosynthetic organisms have developed various light-harvesting antennae surrounding the core complexes of two photosystems (PSs).
Photosynthetic reaction centre - Wikipedia
Electron micrograph of a 2D crystal of the LH1-Reaction center photosynthetic unit. A photosynthetic reaction center is a complex of several proteins, biological pigments, and other co-factors that together execute the primary energy conversion reactions of photosynthesis.Molecular excitations, either originating directly from sunlight or transferred as excitation energy via light …
