1. The CO2 consumer in the Calvin cycle is 1,5-ribulose bisphosphate.
2. The first stable compound produced in this cycle is 3-phosphoglyceric acid with three carbons.
3. This cycle occurs at higher concentrations of CO2 (50-150 ppm).
4. The cycle occurs at low temperatures (10-250C).
5. The cycle occurs only in mesophyll chloroplasts. ie occurs in the stroma of chloroplasts.
6. This happens in low light.
7. It mainly occurs in cold climate plants.
8. The process occurs in C3 and C4 plants.
9. The CO2 fixing enzyme in this cycle is Rubisco.
10. Photorespiration occurs in plants during this cycle.
11. The rate of photosynthesis of plants in this cycle is low.
