1. 3.13 The Calvin Cycle

2. The Calvin Cycle Terms Carbon Fixation – stick CO2 together
Rubisco – enzyme that fixes carbon
Stroma – fluid space in chloroplast
RuBP cycle G3P is 3 carbons

3. The Calvin Cycle Carbon Fixation Products 3 CO2 combined
Rubisco enzyme
Where: Stroma
Products
1 G3P
Rubisco still there
RuBP cycle G3P is 3 carbons

4. Biological Cycles
Rubisco cycle NADPH cycle ATP cycle

5. CO2 vs. Water
Stomata
CO2 in
H2O out
C3 vs C4 vs CAM

6. CO2 vs. Water
Save water = close stomata Store CO2 to be efficient Long or short term

7. 3.14 Overview

8. Light Matters
What light wavelength does chlorophyll a absorb most? What about carotenoids? Where does the least photosynthesis occur?

9. What temperature causes the highest rate of photosynthesis
What temperature causes the highest rate of photosynthesis? What happens to the rate of photosynthesis as the light intensity increases?

10. Metabolism Practical Bromothymol blue is an indicator
Oxygen present = Blue
CO2 present = Yellow
If I breathe into a bromothymol solution it would be…

11. Metabolism Practical

After 8 hours of nighttime?
