Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma. This damage will have the most direct effect on which of the following processes?
A) the splitting of water
B) the absorption of light energy by chlorophyll
C) the flow of electrons from photosystem II to photosystem I
D) the synthesis of ATP
E) the reduction of NADP⁺

Quizplus · Accepted Answer

The puncture of the thylakoid will disrupt the proton gradient that is necessary for the synthesis of ATP via chemiosmosis. This is because the proton gradient is established by the movement of protons from the stroma into the thylakoid lumen, and this movement is facilitated by the electron transport chain. Without a functional thylakoid membrane, the proton gradient cannot be maintained, which means that ATP synthesis will be directly affected.
