Unit 5

Photosynthesis and Cell Respiration

1. Where in the leaves does photosynthesis occur?

Cell

2. What organelle does photosynthesis occur in?

chloroplasts

3. What is required for this process to occur?Light (dependent)

4. What is the space inside the chloroplast?stroma

5. Where is the chlorophyll located?

Thykaloid discs for light dependentreaction

6.What chemical absorbs light?

Chlorophyll in the Thylakoid discs

7.What is the only color that the chlorophyll does NOT absorb?

Green because it is reflected

8. What color do we see & why?

• Green because it is reflected.

9. In the light dependent section, what comes in and what is released?

( H2O is converted to O2)

10. What two molecules are transferred to the next process?

-ATP (energy)-NADPH (electron carriers)

11. What energizes the electrons in the electron transport chain?

light

12. What carries the high-energy electrons to the next process?

NADPH

13. What is energy called in this process?

ATP

14. Light dependent process makes a lot of energy, what is the down side of this process?

Energy is not stable enough to store for more than a few minutes

15.What is not required in the Calvin Cycle process?

Light (independent)

16. What is the purpose of the Calvin Cycle?

Use NADPH & ATP from light reaction with carbon dioxide to mike high-energy sugar for storage

17. What is the other name for the light independent reaction?

Calvin Cycle

18. Where in the chloroplast does the light independentcycle occur?

Stroma

19. Why does the cycle have to go around 6 times?

To pick up 6 carbons

20. Who uses the sugar/glucose?The plants and those that consume the plant for energy

21. Write out the formula. 6CO2 + 6H2O+ (sunlight) = C6H12O6 + 6O2

22. Write out the formula in word form (include # of molecules).

6 carbon dioxide +6 water with sunlight=1 glucose+6oxygen

23.What is stored glucose called (from the movie notes)?

starch

24. What 3 things affect the rate?

-temperature-water

-intensity of light

25. What is the location where most chloroplast is located?

mesophyll

26. What is the vascular system that brings water up from the roots?

xylem

27. What part of the vascular system carries sugar and nutrients?

phloem

28. What is the waxy covering?

cuticle

29. What type of cell respiration requires oxygen?

aerobic

30. What type of cell respirationdoes not require oxygen?

anaerobic

31.Write out the formula.

C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP

32. Write out the formula in word form (don’t forget to include the # of molecules).

1 glucose + 6 oxygen = 6 carbon dioxide + 6 water + ATP

33. What organelle does most of cellular respiration occur?

mitochondria

34. Glycolysis breaks down _______________ into __________________ (include number of molecules).

glucose2 pyruvic molecules

35. Where does Glycolysis occur?

cytoplasm

36. How many ATP molecules does it produce?

2

37. Which stage that is in both aerobic and anaerobic cell respiration does not require oxygen?

glycolysis

38. Where does the Krebs cycle occur?

matrix of the mitochondria

39. How many ATP does it produce?

2

40. During the electron transport chain, it uses _____ to make _____ and _____ in the _________ part of the mitochondria.

O2 H2O ATP

cristae

41. What two processes REQUIRE oxygen?

-Krebs-Electron Transport Chain (ETC)

42. Glycolysis makes 2 molecules of ATP Krebs Cycle makes 2 molecules of ATP Electron Transport chain makes 32 molecules of ATP
