2. 2 Every chemical reaction starts with ______ and results in _______.

3. 3 Reactants, products

4. 4 Give the overall reaction of cellular respiration.

5. 5 Cellular Respiration: 6O 2 + C 6 H 12 O 6  6CO 2 + 6H 2 O + Energy

6. 6 Give the overall reaction of photosynthesis.

7. 7 Photosynthesis: 6CO 2 + 6H 2 O + Energy  6O 2 + C 6 H 12 O 6

8. 8 What is the main purpose of photosynthesis?

9. 9 Plants make sugar (food) so they can have it as energy

10. 10 List the chemical reactions steps of cellular respiration & photosynthesis.

11. 11 CR with oxygen: glycolysis, krebs cycle, electron transport chain Photo: light dependent reactions, light independent reactions(Calvin cyle).

12. 12 What organisms do anaerobic respiration?

13. 13 Yeast and other microorganisms

14. 14 Who does aerobic respiration?

15. 15 You, me, your pet

16. 16 How is sugar broken down during CR?

17. 17 Done in 3 steps slowly to release energy throughout the day

18. 18 Label this organelle

19. 19 A- stroma B-grana C-thylakoid

20. 20 Explain what occurred during the 2 labs we did in class

21. 21 Answers may vary; Cellular respiration rate increased while we did exercise since we need more energy. We broke down more sugar releasing more CO 2 changing bromothymol quicker The balloons increased in size as yeast did anaerobic respiration breaking down the sugar and releasing CO 2

22. 22 When is carbon dioxide being released?

23. 23 1 st and 2 nd step during glycolysis and the Krebs Cycle

24. 24 What are the products of glycolysis? Where does it occur in the cell?

25. 25 Pyruvic acid, net of 2 ATP & NADH; cytoplasm

26. 26 How do aerobic & anaerobic respiration differ? What are the 2 types of anaerobic respiration?

27. 27 Aerobic – with oxygen, creates water as waste, creates a lot of ATP Anaerobic – without oxygen, little ATP, can create alcohol or acid as waste

28. 28 Which produces the most energy during cellular respiration?

29. 29 ETC- electron transport chain

30. 30 Draw a mitochondrion & label where Krebs & ETC occur.

31. 31

32. 32 Describe an autotroph & a heterotroph.

33. 33 Autotroph – creates own energy Heterotroph – consumes other organisms for energy

34. 34 Explain the importance of the palisade mesophyll, cuticle & the stomates.

35. 35 palisade parenchyma – full of chloroplasts capture light for photosynthesis cuticle – prevent water loss, decrease transpiration stomates – allow for gas exchange

36. 36 What molecules are made during the light dependent reactions?

37. 37 ATP & NADPH

38. 38 What is made during the light independent reactions?

39. 39 Sugar C 6 H 12 O 6

40. 40 Explain the difference between light dependent and light independent reactions.

41. 41 Light dependent- requires light and water stores energy in NADPH and ATP Light independent- happens in the dark and uses ATP and NADPH to make sugar needs CO 2

42. 42 What is ATP? Structurally? Where is ATP synthase located?

43. 43 Adenosine triphosphate; adenosine, ribose sugar, 3 phosphate groups (unstable) Along thylakoid membrane & cristae of mitochondria

44. 44 In cells what can ATP be used for specifically?

45. 45 ATP can be used for active transport, synthesis of proteins & nucleic acids, light & nervous system neurotransmitters

46. 46 List the electron carrier(s) for photosynthesis.

47. 47 NADP +

48. 48 List the electron carrier(s) for cellular respiration.

49. 49 NAD + and FAD +

50. 50 List the factors that affect photosynthesis.

51. 51 Light intensity, temp, water.
