Vedclass · Answer

(B) In the light-dependent reactions of photosynthesis,the two photosystems,$PS-II$ and $PS-I$,work in series.$PS-II$ (Photosystem $II$) absorbs light at $680 \ nm$ and initiates the electron transport chain.Electrons are excited in $PS-II$ and passed through a series of electron carriers to $PS-I$ (Photosystem $I$).Therefore,the flow of energy and electrons occurs from $PS-II$ to $PS-I$ in the non-cyclic photophosphorylation process ($Z$-scheme).

When the two pigment systems absorb light,in what direction does the energy flow between them?
