Question

What is cyclic electron transport ?

Answer 1

Cyclic electron transport is a light‐driven flow of electrons through a photosyntheticreaction centre with the electrons returning to the reaction centre via an electron transport pathway. Cyclic electrontransport will normally generate an electrochemical potential (typically pH) gradient across a membrane but does not result in the net production of reductant. The pH gradient generated may drive the production of adenosine triphosphate (ATP) (cyclic photophosphorylation) or may regulate photosynthesis.
