CThylakoid membrane of the chloroplast
DMitochondrial matrix of leaf cells
Answer & Solution
Correct answer: B. Stroma of the chloroplast organelle
Calvin cycle (dark reactions / carbon-fixation cycle) occurs in the stroma where its enzymes including RuBisCO are located.
It uses the ATP and NADPH produced by the light reactions on the thylakoids.
