Compare and contrast the cyclic and noncyclic electron transport pathways of photosynthesis. What will be an ideal response?
Both cyclic and noncyclic electron transport involve photosynthetic pigments embedded in
the thylakoid membranes as well as the flow of electrons down an electron transport chain
resulting in the generation of ATP via chemiosmosis. Cyclic electron transport does not
involve the reduction of NADP.+ Instead, electrons flow in a cyclical pathway from
photosystem I to the electron transport chain and back to photosystem I. By contrast,
noncyclic electron flow involves the linear flow of electrons from water to photosystem II,
down an electron transport chain to photosystem I, and finally to NADP+. Consequently, the
noncyclic pathway results in the formation of O2, but the cyclic pathway does not.
