Identify the incorrect statements among the following I. When only PS I is functional, cyclic flow of electrons is not possible II. The breakdown of the gradient provides enough to make the enzyme synthesis III. The NADP reductase enzyme is located on the thylakoid membrane IV. Proton gradient increases due to PC and Cyt f.
I, II, III
I, III, IV
II, III, IV
I, II, IV
Correct Answer
Detailed Explanation
Statement I is incorrect because cyclic electron flow is possible with only PS I. Statement III is incorrect because NADP reductase is located on the stroma side of the thylakoid membrane, not on the membrane itself. Statement IV is incorrect because the proton gradient is primarily due to the activity of the cytochrome b6f complex, not PC and Cyt f.
