Question

Where does cyclic photophosphorylation take place in leaves? Explain the events in sequence .Why is the process called cyclic?

Answer 1

Cyclic phosphorylation occurs inside the thylakoid membrane of the chloroplast in the leaves.  In it basically electrons are recycled, the thylakoid membranes have photo-systems that contain chlorophyll, this chlorophyll helps in the absorption of light energy. This light energy is used to excite the electrons, the excited electron is transferred to the electron acceptor protein from there it is passed through the electron transport chain.

As the electron passes from the electron transport chain, it looses its energy and this energy is used to synthesize the energy currency i.e. ATP from ADP. The electron whose energy was lost is recycled and transferred to the photo-system again, thus forming a cycle. That's why this process is called cyclic phosphorylation.
