Presentation Transcript

  1. Photosynthesis

  2. Let’s Get Absorbed - 100 Chloroplasts may contain a variety of these light-absorbing compounds, such as chlorophyll a

  3. Let’s Get Absorbed - 100 What are pigments?

  4. Let’s Get Absorbed - 200 Light boosts them to high-energy states to kick off photosynthesis

  5. Let’s Get Absorbed - 200 What are electrons?

  6. Let’s Get Absorbed - 300 Even though most leaves look green on the outside, you’re actually looking through a transparent layer to these chloroplast-containing cells just under the leaf’s surface

  7. Let’s Get Absorbed - 300 What are mesophyll cells?

  8. Let’s Get Absorbed - 400 Chlorophyll b and carotenoids are examples of these pigments that do not participate directly in photosynthesis, but instead assist by absorbing additional colors of light

  9. Let’s Get Absorbed - 400 What are accessory pigments?

  10. Let’s Get Absorbed - 500 Ultraviolet light and infrared light are found on either side of visible light in this range that includes many other forms of radiation

  11. Let’s Get Absorbed - 500 What is the electromagnetic spectrum?

  12. Knowing Your ATPs - 100 Also a part of your DNA, it’s the 5-carbon sugar molecule found in ATP

  13. Knowing Your ATPs - 100 What is ribose?

  14. Knowing Your ATP’s - 200 Not ATP, but this, is the long-term energy storage molecule in living things

  15. Knowing Your ATP’s - 200 What is glucose?

  16. Knowing Your ATP’s- 300 Energy released from ATP breakdown can be used to contract muscles, build large organic molecules, or carry out this cellular process

  17. Knowing Your ATP’s - 300 What is active transport?

  18. Knowing Your ATP’s- 400 In order for ATP to be produced during the light reactions of photosynthesis, these must supply the energy by diffusing through ATP synthase

  19. Knowing Your ATP’s - 400 What are H+ ions?

  20. Knowing Your ATP’s- 500 For every rotation of the Calvin Cycle, 9 ATP molecules are used. This many ATP molecules are needed for the production of 2 glucose molecules

  21. Knowing Your ATP’s - 500 What is 36?

  22. Light It Up - 100 It’s the part of a chloroplast where the light reactions of photosynthesis take place

  23. Light It Up- 100 What is the thylakoid membrane?

  24. Light It Up - 200 Chlorophyll a absorbs this color of light in both photosystems

  25. Light It Up- 200 What is red?

  26. Light It Up - 300 If this man hadn’t shed any light on the subject, we might still think that plants produce oxygen at night

  27. Light It Up - 300 Who is Ingenhousz?

  28. Light It Up - 400 Photosynthesis would quickly stop without the generous electron donations this molecule makes to photosystem II

  29. Light It Up - 400 What is water?

  30. Light It Up - 500 One of three products from the light reactions, it carries high-energy electrons to the Calvin Cycle

  31. Light It Up - 500 What is NADPH?

  32. Calvinism - 100 Because reactions of the Calvin Cycle happen “free” of light, this term is often used to describe them

  33. Calvinism - 100 What are light-independent reactions?

  34. Calvinism - 200 Melvin Calvin might have been quite confused about how carbohydrates were produced if this molecule didn’t enter the process right away

  35. Calvinism - 200 What is CO2?

  36. Calvinism - 300 This type of plant must store CO2 in organic acids during the night if it wants to produce glucose all day long

  37. Calvinism - 300 What is a CAM plant?

  38. Calvinism - 400 A common misconception, this molecule is not actually a product of the breakdown of CO2, but is instead a product of H2O breakdown during the light reactions

  39. Calvinism - 400 What is oxygen?

  40. Calvinism - 500 For every rotation of the Calvin Cycle, 6 NADPH molecules are used. This many NADPH molecules are needed for the production of 1 molecule of glucose

  41. Calvinism - 500 What is 12?

  42. Which Comes First? - 100 Light-dependent reactions, production of glucose, light-independent reactions

  43. Which Comes First? - 100 What are light-dependent reactions?

  44. Which Comes First? - 200 Photosystem I, Photosystem II, ATP synthase

  45. Which Comes First? - 200 What is photosystem II?

  46. Which Comes First? - 300 Use of ATP, splitting of water, Use of CO2

  47. Which Comes First? - 300 What is splitting of water?

  48. Which Comes First? - 400 Production of NADPH, production of glucose, production of O2

  49. Which Comes First? - 400 What is production of O2?
