Where does the Calvin cycle occur, and what does rubisco do there?
Answer and explanation
Correct answer: A. In the stroma, where rubisco fixes carbon dioxide
- Step 1: The Calvin cycle takes place in the stroma of the chloroplast. Step 2. Rubisco attaches carbon dioxide to ribulose bisphosphate. Answer: the stroma, where rubisco fixes CO2. Why not the others: Mitochondria carry out cellular respiration and ATP synthesis; lysosomes digest macromolecules through acid hydrolases; and chloroplasts carry out photosynthesis in plant cells.
