Vedclass · Answer

(A) Cyclic photophosphorylation occurs when only light of wavelengths beyond $680 \ nm$ is available for excitation,or when the activity of $PS-II$ is inhibited.In this process,the electron is circulated within the $PS-I$ photosystem.The excited electron from the reaction center $P700$ of $PS-I$ is passed to an electron acceptor and then travels through the electron transport system back to $PS-I$.During this transport,$ATP$ is synthesized from $ADP$ and inorganic phosphate.Therefore,only $PS-I$ is involved in cyclic photophosphorylation.
