Creating a proton gradient across the thylakoid membrane in higher plants uses cyclic electron flow (CEF), which primarily serves two purposes: (1) producing ATP and balancing the ATP/NADPH energy budget; and (2) defending photosystems I and II from photoinhibition.
ATP and NADPH are produced by noncyclic electron transport. The single product of cyclic electron transport was ATP. Both steps are required by a plant to produce the required amount of ATP for the Calvin Cycle. The electrons are released by photosystem I and then brought back into the system during cyclic photophosphorylation. However, in non-cyclic photophosphorylation, the electrons that the photosystems emit do not come back.
