In Chloroplasts,chemiosmosis Translocates Protons From

Question

In chloroplasts,chemiosmosis translocates protons from
A)the stroma to the photosystem II.
B)the matrix to the stroma.
C)the stroma to the thylakoid space.
D)the intermembrane space to the matrix.
E)the thylakoid space to the stroma.

Accepted Answer

Chemiosmosis is the process that drives ATP synthesis in the thylakoid membrane of the chloroplasts. In this process, protons are translocated from the stroma to the thylakoid space, forming a proton gradient that is used by ATP synthase to produce ATP. Therefore, the correct option is C, which states that protons are translocated from the stroma to the thylakoid space.
