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. ... Because of these effects, DCMU is often used to study energy flow in photosynthesis.
Why do we use DCMU quizlet?
DCMU is as an herbicide; it blocks the transfer of electrons out of photosystem II.
How would DCMU affect the formation of ATP?
So DCMU totally blocks the LEF and results in no ATP and NADPH production from LEF. DBMIB also blocks the CEF and results in 0 ATP and NADPH production from photosynthesis. Instead, the inhibitions do indeed result in the generation of reactive oxygen species in the chloroplast.
