Cyclic photophosphorylation is performed by PS-I only. In this process, an electron expelled by the excited photo centre, ie, P700 is returned to it after passing through a series of electron carriers.
PS- I is located on both the non- appressed part of grana thylakoids as well as stroma thylakoids, while PS-II is located in the appressed part of grana thylakoids only, stroma thylakoids lack PS-II.
