### Photosynthesis Educational Resource
#### Calvin Cycle Worksheet
**13.** Draw the complete pathway of the Calvin cycle reactions. Indicate where the investment of ATP, CO₂, and NADPH come into the cycle.
**14.** What is the enzyme that “fixes” carbon in the Calvin cycle?
**15.** What environmental input is necessary for the Calvin cycle reactions?
**16.** What is regenerated in the Calvin cycle reactions?
**17.** What is the primary product of the Calvin cycle reactions?
**18.** The carbons for the product above come from
---
### Additional Photosynthesis Context
**19.** In most plants, a buildup of oxygen occurs when [stomata] are closed.
When oxygen rises in a plant, it combines with the enzyme [RuBisCO].
This process is called [photorespiration].
**20.** Did the Calvin cycle reactions evolve when the concentration of atmospheric oxygen on earth was low or high?
**21.** What spatial and/or temporal adaptations allow C₄ and CAM plants to survive arid (dry) conditions better than C₃ plants?
- **a. C₄:**
- **b. CAM:**

5. **In 1882, T.W. Engelmann conducted an experiment to test which wavelengths of light are important for photosynthesis.** He placed a strand of *Spirogyra* (a filamentous green alga) across a glass slide. He illuminated the slide with a spectrum of colors created by a crystal prism. He then added a drop of water containing bacteria that use aerobic respiration.
