WebHow does DCMU affect synthesis of ATP and NADPH? 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.
