Answer:
Explanation:
1. Over time more and more molecules of DCPIP would be decreased by electrons taken from plastoquinone (Pq). This statement is true in the sense that DCPIP is an artificial electronic acceptor which is decreased by taking electrons from plastoquinone.
2.) Water splitting by Photosystem II would occur at higher levels than if the drug were administered without DCPIP. This statement is true.
3.)Events in Photosystem I would occur just as they would in the absence of drug and DCPIP. This statement is false because the drug obstructs the electron transport from plastoquinone to cytochrome B. So the events are abnormal because no protein transfer is involved in this mechanism.
