Which of the following is correctly labelled for the given figure?
Which of the following is correctly labelled for the given figure?
The correct option is B
A: PS II; B: PS I; C : E- acceptor; D: LHC
The light-harvesting complex of the photosystem is made up of hundreds of pigments molecules containing all pigments (except single chlorophyll a molecules) also called antennae. The antenna molecules absorb light of a shorter wavelength than that of the photo centre. On absorption of light energy, the antenna molecules get excited. The excited antenna molecules hand over their energy to core molecules which in turn supply that energy to the photo centre.
Electron released during photolysis of water is picked up by photo centre of PS II called P680. The extruded electron passes through a series of electron carriers—pheophytin, PQ, cytochrome b - f complex and plastocyanin. While passing over the cytochrome complex, the electron loses sufficient energy for the synthesis of ATP The electron is handed over to photo centre P700 of PSI by plastocyanin. P700 extrudes the electron after absorbing light energy.
The extruded electron passes through special chlorophyll X, Fe-S, ferredoxin, to finally reach NADP+. The latter then combines with (released during photolysis) with the help of NADP-reductase to form NADPH.
