We shall discuss reaction centres and the photosystems later in this tutorial. The apoprotein with its chromophore is called phycocyanin, phycoerythrin, and allophycocyanin, respectively. They enhance the amount and spectral window of light absorption and fill the "green gap", which occur in higher Plants. There is a central core of allophycocyanin , which sits above a photosynthetic reaction center. There are phycocyanin and phycoerythrin subunits that radiate out from this center like thin tubes.
This increases the surface area of the absorbing section and helps focus and concentrate light energy down into the reaction center to a Chlorophyll.
From Wikipedia, the free encyclopedia. Redirected from Light harvesting complex. Main article: Bacterial antenna complex.Little light reaches algae that reside at a depth of one meter or more in seawater, as light is absorbed by seawater. A phycobilisome is a light-harvesting protein complex present in cyanobacteria, glaucocystophyta, and red algae and is structured like a real antenna.
