Which technique has helped in investigation of Calvin cycle?

1. X-ray crystallography
2. X-ray technique
3. Radioactive isotope technique
4. Intermittent light

Correct answer: Radioactive isotope technique

Solution

Radioactive isotope technique helped scientists track the fate of carbon atoms in the Calvin cycle, revealing the sequence of intermediates and reactions. By using labeled CO2, they could identify which compounds formed first and how carbon was fixed.
