Question

where does the calvin cycle take place?

○ stroma of the chloroplast
○ thylakoid membrane
○ outer membrane of the chloroplast
○ interior of the thylakoid (thylakoid space)

Explanation:

The Calvin cycle, which is the light - independent reaction of photosynthesis, occurs in the stroma of the chloroplast. The thylakoid membrane is the site of the light - dependent reactions. The outer membrane of the chloroplast is a protective layer and not directly involved in the Calvin cycle. The interior of the thylakoid (thylakoid space) is where protons accumulate during the light - dependent reactions.

Answer:

stroma of the chloroplast
