Question

Which of the following processes would be most directly affected if a thylakoid membrane is punctured so that the interior of the thylakoid is no longer separated from the stroma?
a. synthesis of ATP
b. flow of electrons from photosystem II to photosystem I
c. splitting of water
d. reduction of NADP+

Answer 1

Answer:

Synthesis of ATP would be directly affected (correct answer A)

Explanation:

While photosynthesis and the electron transport in thylakoid-membrane occur, a gradient in proton concentration is made. Then, this protons go through a protein complex (ATPasa, present in thylakoid membrane) down a concentration gradient into stroma, and this potential energy is used to synthesize ATP (energy for the cell).
