Vedclass · Answer

(A) In cyclic photophosphorylation,only $PS-I$ is functional. The excited electrons are passed from the reaction center to an electron transport system and finally return to $PS-I$. During this process,the electrons move downhill in terms of redox potential,which releases energy used to synthesize $ATP$ from $ADP$ and inorganic phosphate. Thus,$A$ refers to $ATP$ and $B$ refers to downhill redox potential.

$PS-I$ in cyclic photophosphorylation is involved in the formation of ...$A$... by ...$B$... movement of electrons. What do $A$ and $B$ refer to here?
