Question

Photosystem II inhibitors are a common type of herbicide used for the control of many broadleaved weeds as well as some grasses. Most of these herbicides function by blocking the electron transport chain, something that's often achieved through binding of the herbicide to the D1 reaction center proteins of the secondary quinone acceptor site. This inhibits the reduction of plastoquinone. Explain why this would make it impossible for the plant to synthesize sugar molecules from G3P. Please include details on all relevant steps of the light-dependent reactions in your answer.
