Dec 26, 2017
A photosystem is a complex in which photosynthetic pigments are arranged in the form of clusters for the efficient absorption and utilization of sunlight energy in thylakoid membranes.
Explanation:
Photosystem constitutes two main parts. A brief concept to them is as follows:
- Antenna Complex:
It is a light- harvesting complex containing proteins and many molecules of#"cholorophyll a"# ,#"cholorophyll b"# and#"carotenoids"# . Photons of light are first absorbed by antenna complex pigments which then transfer the energy to the reaction center. - Reaction Center:
It has one or more molecules of#"cholorophyll a"# along with primary electron acceptor and associated electron carriers of electron transport system.
It receives the absorbed sunlight energy from the antenna complex and convert that energy into#"chemical energy"# .
