Photosynthesis and Cellular Respiration Test Review



Photosynthesis and Cellular Respiration Test Review

Photosynthesis:

1. What is the chemical equation for photosynthesis?

Sunlight

6CO2+6H2O ( C6H12O6+6O2

2. Where does photosynthesis occur? Chloroplast

3.Where do the light-dependent reactions occur? Thylakoid

4. What do the light-dependent reactions start with? Sunlight splitting water

What do two things does this reaction produce? Oxygen and ATP

5. Where do the light-independent occur? Stroma

6. What do the light-independent reactions start with? Carbon Dioxide and ATP

What does it end up producing? Glucose

7. Draw the illustration we did in class showing the process of photosynthesis.

8. How is oxygen released from the leaf? Through the stomata

9. Draw and label the chloroplast.

10. What is the point of photosynthesis? To produce Glucose for the plant to use

11. Describe the three experiments we discussed about the early discovery of photosynthesis.

Planted tree, observed for 5 years, soil not eaten.

Candle under jar goes out, candle with plant under jar stays lit.

Aquatic plants release oxygen bubbles when exposed to light.

Cellular Respiration:

12. What types of organisms do cellular respiration? All organisms

13. What are the two types of cellular respiration? Aerobic and Anaerobic Respiration

14. Both Aerobic and Anaerobic Respiration begin with what? Glycolysis

15. Explain what happens in Glycolysis (you can draw the picture we drew on the board in class also but explain it in words too.)

Glucose is spilt into 2 pyruvates using 2 ATP.

16. What does Glycolysis do and what does it produce? Anaerobic reaction and it produces 2 net ATP, 2 pyruvates

17. If oxygen is present, where does the pyruvate go next? Kreb’s Cycle

18. Explain the Kreb’s Cycle or the Citric Acid Cycle. (You can draw the picture we drew in class but explain it in words too).

Pyruvate is turned into Acetyl CoA before entering the Kreb’s Cycle. The Kreb’s cycle is two complete turns that produces NADH, 2 ATP, and Carbon Dioxide

19. What does the Kreb’s Cycle breakdown? Pyruvate

20. What does the Kreb’s Cycle produce? 4NADH, 2 ATP, 2FADH2 Carbon Dioxide is a waste product that we exhale

21. How many ATP are made in the Kreb’s Cycle? 2

22. Explain the Electron Transport Chain. (You can draw the picture we drew in class but explain it in words too).

Electrons are passed down the chain and are accepted by oxygen at the end which creates water.

[pic]

23. How many ATP are made in the electron transport chain? 32 ATP

24. What is the final electron acceptor? Oxygen

25. How is water made at the end of the electron transport chain? Oxygen accepts the electrons and hydrogen bonds to the oxygen

26. Where do the 36 ATP made in aerobic respiration come from? 2 Glycolysis, 2 Kreb’s Cycle, and 32 ETC

27. If oxygen is not available, what type of cellular respiration do we do? Anaerobic Respiration

28. What are the two types of anaerobic respiration? Alcoholic Fermentation and Lactic Acid Fermentation

29. What is made in alcoholic fermentation? Give me an example of an organism that does this.

Ethyl alcohol, Carbon Dioxide, and ATP. Yeast does this.

30. When do humans do lactic acid fermentation? When oxygen is not abundant. (exercising)

31. What causes our muscles to be sore? Lactic Acid build up

32. Is anaerobic respiration good at making a lot of ATP? No

33. Compare and contrast aerobic and anaerobic respiration.

Aerobic: requires oxygen

Makes lots of ATP

Breaks down glucose

Anaerobic: no oxygen

Makes little ATP

Breaks down glucose

34. What is the chemical equation for aerobic respiration? C6H1206+6O2(6CO2+6H2O+36ATP

35. What are some differences between photosynthesis and cellular respiration?

Photosynthesis makes glucose and cellular respiration breaks it down.

Photosynthesis makes oxygen and cellular respiration needs it.
