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?

WebDiuron (DCMU) inhibits photosynthesis by blocking electron transport in phosystem II (PSII), eventually causing immediate disruption in the symbiosis between zooxanthellae and host coral (Råberg ... WebIn general, these herbicides inhibit photosynthesis by binding to D1 proteins of the photosystem II complex in chloroplast thylakoid membranes. Herbicide binding at this …
WebThe influence of the herbicide, DCMU, on the oxygen-evolving system of photosynthesis Biochim Biophys Acta . 1958 Jan;27(1):205-6. doi: 10.1016/0006-3002(58)90313-5. WebBy inhibiting the binding of PQ, the process of photosynthetic electron transfer is interrupted, and the synthesis of ATP and NADPH in the chloroplast is compromised. This results in an inability to fix CO 2 and produce the nutrients needed for the plant to survive.
