The scheme outlines coupled photosystems of plants. Indicated is the impact of a commonly used herbizide, which interferes with the ability of plastoquinone (PQ) to bind to PSII.

Question i) explain the effect that the indicated herbizide has on the electron transport in the coupled photosystem;

Question ii) name the products of the photosynthesis light reactions which are not produced anymore in the presence of the shown herbizide, and

Question iii) give two reasons why plants die when treated with this herbizide.

Question iv) would you predict this herbizide to interfere with the functioning of the mitochondrial electron transport chain, justify your answer?
