6. Writing Assignment Page 9 summary 1-20
It’s a hard life being me. I am an electron in the light rxns. My life as a free electron is short lived and I am constantly being moved around and taken advantage of by integral proteins. It all began when a water molecule split apart and gave me a new life as a free electron, but no sooner was I released than photosystem II was scooping me up and…

13. 2 Stages of Photosynthesis
Light Reactions and Calvin Cycle 13

14. Calvin Cycle
Process by which enzymes are used to produce sugars (occurs in stroma)
Does not need light (but usually happens during the day)
Carbon Fixation – process of taking in carbon to make sugars
Cycle in which CO2, ATP and NADPH are used to create carbohydrates
The NADP+ and ADP then goes back to the light reactions to be “recharged” 14

15. Diagram 15

16. Summary of Photosynthesis:
Balanced equation =
6CO2 + 6H2O  C6H12O6 + 6O2 16

18. Notes Pages 10 & 11

19. Review: What is the used cellular energy
Adenosine Triphosphate (ATP)
Composed of 3 parts:
Nitrogen base (adenine)
sugar (ribose)
3 phosphate groups. 19

20. Review: How is energy released from ATP?
A phosphate bond is broken
ATP  Energy + ADP + 1 phosphate group
One phosphate bond has been removed 20

21. Energy Release Summary

22. Question of the Day
1-27
How are the light reactions and the Calvin Cycle connected (what are the intermediates)?

27. Warm Up 1/20
If a plant is left in the dark for a significant amount of time, what will happen to glucose production? What will the plant do to survive
Today:
Quiz on photosynthesis
Discuss how plants store extra carbs.
Discuss effects on photosynthesis
Tomorrow: Seat change!

28. Some extras?
Extra Food
Plants make extra carbohydrates which are stored as starch (like a potatoes)
These carbohydrates are what heterotrophs rely on for survival

30. What are Some Effects on Photosynthesis?
Water
Light Intensity
CO2 Levels
Temperature

32. Alternative Pathways
There are different methods in which plants create carbohydrates (we discussed the most common)
Plants in dry climates use the C4 pathway or CAM pathway
Why?
Both deal with controlling water loss
Why do cactus have “ridges”?

33. The End!

34. Warm Up 1-22 What are four factors that can limit photosynthesis?
