Question

6) In mitochondria, chemiosmosis translocates protons from the matrix into the intermembrane space, whereas 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.

Answer 1

Answer:

C

Explanation:

1. Chloroplast is the green organelle in the plants in which photosynthesis occurs, through which plants made food autotrophically by photosynthesis.

2. Chemiosmosis:  the mechanism in which the ions, such as H+  move across a  membrane, ions moves down their electrochemical gradient.

3. The generation of adenosine triphosphate (ATP) by the  transfer of H+ across a membrane during photosynthesis in which chemiosmosis translocates protons from the stroma to the thylakoid space.
