Chloroplasts are organelles with areas that conduct different specialized activities.
Where in the chloroplast do the light reactions and the Calvin cycle occur?
Answer:
The light reactions of photosynthesis occur along the thylakoid membrane. The Calvin cycle occurs in the stroma, surrounding the thylakoids.

Extended Response
The reactions of photosynthesis make up a biochemical pathway.
Part A What are the reactants and products for both the light reactions and the Calvin cycle?
Part B Explain how the biochemical pathway of photosynthesis recycles many of its
own reactants, and identify the recycled reactants.
Chapter 6 Standardized Test Prep
Extended Response, continued
Answer:Part A The reactants for the light reactions of
photosynthesis are sunlight, water, NADP+, and ADP. The products are oxygen, ATP, and NADPH. The reactants for the Calvin cycle are ATP, NADPH, CO2, and RuBP. The products are NADP+, ADP, and organic compounds.
Part B ADP/ATP, NADP+/NADPH, and electrons are recycled during photosynthesis. RuBP, which reacts with CO2 in the Calvin cycle, is regenerated at each turn of the cycle.
