Detailed explanation-1: -DCMU is a very specific and sensitive inhibitor of photosynthesis. It blocks the QB plastoquinone binding site of photosystem II, disallowing the electron flow from photosystem II to plastoquinone.
Detailed explanation-2: -DCMU blocks photosynthetic electron flow from photosystem II to the PQ pool. DBMIB blocks photosynthetic and respiratory electron flow [which are intermingled in the thylakoid membrane of cyanobacteria (Schmetterer 1994)] from the PQ pool to cytochrome b6f (Fig. 1A).
Detailed explanation-3: -DCMU is a photosynthesis inhibitor that is very precise and sensitive. It blocks photosystem II’s QB plastoquinone binding site, preventing electron flow from photosystem II to plastoquinone.
Detailed explanation-4: -The photosynthesis inhibitors include these herbicide families: Triazine. Triazinone. Phenylurea.
