Chloroplasts are disrupted and the stroma separated from the lamella. The isolated stroma will fix CO$_2$, if it is supplied with:
Show Hint
- ATP and NADPH
- Oxygen
- Light
- Carotenoid
The Correct Option is A
Solution and Explanation
Calvin cycle requirements:
Stroma contains all enzymes for CO$_2$ fixation
Requires energy (ATP) and reducing power (NADPH)
Light not needed directly (dark reactions)
Oxygen inhibits RuBisCO activity
Carotenoids are light
harvesting pigments
