Question

question 8 of 10
the diagram summarizes the events of the light reactions.
based on the diagram, where are hydrogen ions found within a chloroplast?
a. in the electron transport chains only
b. in the electron transport chains and the photosystems
c. in the thylakoids only
d. in the stroma and the thylakoids

Explanation:

In the light - reactions of photosynthesis in chloroplasts, hydrogen ions are pumped into the thylakoid space during the electron transport chain process and are also present in the stroma. The thylakoids are the site where the initial separation and movement of hydrogen ions occur, and they can also be found in the stroma as part of the overall chemical environment of the chloroplast.

Answer:

D. In the stroma and the thylakoids
