Answer: C3 cycle or dark reaction.
- A Light-dependent reaction
- B C3 cycle or dark reaction
- C Krebs cycle for plants
- D C4 pathway
Correct answer: B. C3 cycle or dark reaction
Explanation: Calvin cycle = C3 pathway = dark reaction (or light-independent reaction). First stable product is 3-carbon PGA (3-phosphoglycerate).
Simplified photosynthesis diagram: light energy, CO2, and H2O enter the leaf and are converted in the chloroplast into glucose and O2.
Concept context
Light reactions, the Calvin cycle, C 3 /C 4 /CAM pathways, photorespiration, and factors affecting the rate of photosynthesis. One of the highest-yield NEET chapters.
