Vedclass · Answer

(A) In the light-dependent reactions of photosynthesis,the two photosystems ($PS-II$ and $PS-I$) work in series to facilitate the non-cyclic electron transport chain ($Z$-scheme).$PS-II$ (P680) absorbs light energy first,leading to the photolysis of water and the release of electrons.These electrons are then transferred through an electron transport system to $PS-I$ (P700).Therefore,the flow of energy and electrons occurs from $PS-II$ to $PS-I$.

When two pigment systems absorb light,the direction of energy flow between them must be:
