Vedclass · Answer

(A) In the light reaction of photosynthesis,the process begins when the chlorophyll molecule in Photosystem-$II$ $(PS-II)$ absorbs light energy (photons).This absorption of light energy leads to the excitation of electrons in the chlorophyll molecule,causing it to lose electrons and become oxidized.This oxidation of chlorophyll is the primary event that triggers the subsequent electron transport chain and the photolysis of water to replace the lost electrons.
