It moves cyclically in cyclic photophosphorylation:

Explanation

In cyclic photophosphorylation, electrons move cyclically through the electron transport chain of the thylakoid membrane. They are returned to the chlorophyll molecule, creating a cyclic flow that generates ATP. Oxygen is not involved in cyclic photophosphorylation. It is produced in non-cyclic photophosphorylation . ATP is produced during both cyclic and non-cyclic photophosphorylation. In cyclic photophosphorylation,NADPH is not produced in significant amounts in cyclic photophosphorylation. It is primarily generated in non-cyclic photophosphorylation.
