A herbicide that blocks electron transport from PS-II to PS-I by inhibiting electron flow between PSII and plastoquinone is______
Open in App
Solution
The correct option is A DCMU
DCMU is a herbicide that acts as a potent inhibitor of PS-II. It inhibits the flow of electrons from PSII to plastoquinone. Paraquat is also a herbicide which inhibits PS-I by producing super oxides. DCPIP is a dye used to measure the rate of photosynthesis. Hence, the answer is DCMU.
