photosynthesis
in chloroplasts, light drives the conversion of water to oxygen and nadp to nadph with transfer of h ions across chloroplast membranes. in mitochondria, it is the conversion of oxygen to water, nadh to nad and succinate to fumarate that are required to generate the proton gradient.









































electron transport chains are major sites of premature electron leakage to oxygen, generating superoxide and potentially resulting in increased oxidative stress.

dcmu









































dcmu (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is an algicide and herbicide of the arylurea class that inhibits photosynthesis. it was introduced by bayer in 1954 under the trade name of diuron.









































section::::mechanism of action.









































dcmu is a very specific and sensitive inhibitor of photosynthesis. it blocks the plastoquinone binding site of photosystem ii, disallowing the electron flow from photosystem ii to plastoquinone. this interrupts the photosynthetic electron transport chain in photosynthesis and thus reduces the ability of the plant to turn light energy into chemical energy (atp and reductant potential).
