Explanation:

light absorbed by LHC 1

excitation of chlorophyll a

electron caught by electron acceptor pheophytin

chla oxidized

splitting of water by water harvesting system

released electrons caught by chla

chla deexcited

electrons from electron acceptor to electron transport system by plastoquinine cycle

for each electron 2H+ from stroma to lumen

again LHC2 takes light

chla of LHC 2 excited

chla of LHC2 is oxidized

it is deoxidised by electrons from electron transport system

electrons released from LHC2 is taken by electron acceptor

those electrons are again taken by FDR enzyme which takes electrons and 2H+ from strom to convert NADP+ to NADPH+

due to this process H+accumulated in lumen

the accumulated H+ will pass through ATPase enzyme which causes rotational change in f1 of atpase enzyme and converts ADP+P to ATP
