1) Dichlorophenyldimethylurea inhibits photosynthesis by blocking electron transfer between the plastoquinone in photosystem II. a) Would you expect this to interfere with cyclic photophosphorylation? b) This herbicide normally stops O2 evolution, but if we add ferricyanide to the chloroplasts, O2 evolution continues.
