The substance dichlorophenyldimethylurea (DCMU) is an herbicide that inhibits photosynthesis by blocking electron transfer between plastoquinones in photosystem II.
(a) Would you expect DCMU to interfere with cyclic photophosphorylation
(b) Normally, DCMU blocks O2 evolution, but addition of ferri-cyanide to chloroplasts allows O2 evolution in the presence of DCMU. Explain.
