Explain the various complexes in Electron transport chain.

Explanation

Electron transport chain in each photosystem involves four complexes :
Core Complex (CC) : CC I in PS I the reaction centre is P700, CC II is PS II the reaction centre is P680.
Light Harvesting Complex or Antenna complex (LHC) :
Two types : LHCl in PS I and LHC II in PS II.
Cytochrome b6 f complex : It is the non - pigmented protein complex connecting PS I and PS II . Plastoquinone (PQ) and Plastocyanin (PC) are intermdiate complex acting as mobile or shuttle electron carries of Electron Transport Chain. PQ acts as shuttle between PS II and Cytochorme `b_(6)` - f complex and PC connects.
Cytochrome `b_(6)` - f and PS I complex.
ATPase complex or Coupling factor : It is found in the surface of thylakoid membrance . This complex is made up of `CF_(1)` and `CF_(0)` factose . This complex utilizes energy form ETC and converts ADP and inorganic phosphate (Pi) into ATP.
