The Calvin cycle occurs in the stroma of the chloroplasts.
The Calvin cycle occurs in the stroma.
The Calvin cycle occurs in the stroma. The stroma is the space within the chloroplasts that is outside of the thylakoid membranes. To find this answer, you can review the process of photosynthesis. The Calvin cycle is the second stage of photosynthesis, following the light-dependent reactions that occur in the thylakoid membranes. During the Calvin cycle, carbon dioxide is converted into glucose using ATP and NADPH produced in the light reactions.
