DCMU is a small molecule that is often used as a herbicide (a chemical to kill plants). DCMU interrupts the electron transport chain in chloroplasts by blocking the donation of electrons by photosystem II.
Explain the biochemical effects you would expect to see if you gave a plant cell DCMU, then measured for the following processes in the chloroplast in about 1 hour.
Specifically, predict if the following processes would increase, decrease or stay the same: Light absorption, production of ATP, production of G3P, usage of ATP. For each prediction, briefly explain why
