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

Question

Quizplus · Accepted Answer

The puncturing of the thylakoid will lead to a loss of the proton gradient required for the synthesis of ATP through chemiosmosis. In normal conditions, proton pumps move H+ ions from the stroma to the thylakoid lumen, creating a gradient that drives ATP synthesis. However, puncturing the thylakoid would eliminate this gradient, hampering ATP synthesis.
