Oxidised chlorophyll

Vedclass · Answer

(C) During the light-dependent reactions of photosynthesis,light energy is absorbed by the antenna complex and transferred to the reaction center,$P680$ (Photosystem $II$).When $P680$ absorbs light,it loses an electron and becomes oxidized $(P680^+)$.This oxidized chlorophyll $(P680^+)$ is a very strong oxidizing agent and has a high affinity for electrons.It extracts electrons from water molecules,causing the water to split (photolysis) into protons $(H^+)$,electrons,and oxygen $(O_2)$.Therefore,the energy required for the photolysis of water is derived from the oxidized chlorophyll.
