How does diuron inhibit photosynthesis
WebHow do inhibitors affect photosynthesis? Photosynthesis inhibitors disrupt the photosynthetic (food producing) process in susceptible plants by binding to specific sites within the photosystem II complex in plant chloroplasts. How does DCMU affect synthesis of ATP and NADPH? WebInhibitors are becoming more common in practice. Addition of inhibitors occur at the end of the light phase after reaching the targeted cellular concentration because they directly interfere the electron flow from PSII to the PQ pool, this cuts photosynthesis and prepares cells for the dark phase to produce H 2 in anaerobic conditions [ 73 ].
