1. Chapter 9 Review

2.  Organisms get the energy they need by breaking down food molecules gradually and capturing their chemical energy.

3.  Fermentation is a stage of cellular respiration.

4.  Krebs cycle - electron transport – glycolysis is the correct sequence of events in cellular respiration.

5.  The correct equation for cellular respiration: 6O 2 + C 6 H 12 O 6 -> 6CO 2 + 6H 2 O + Energy

6.  Cellular respiration releases energy by breaking down ATP

7.  The reactants in the equation for cellular respiration are glucose and oxygen.

8.  Water is a product of cellular respiration.

9.  Cellular respiration is called an aerobic process because it requires glucose.

10.  Anaerobic bacterium organism are NOT likely to carry out cellular respiration.

11.  The fermentation process does NOT release energy from glucose.

12.  Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back is one of the ways that cellular respiration and photosynthesis are opposite processes.

13.  Photosynthesis is to chloroplasts as cellular respiration is to mitochondria.

14.  Unlike photosynthesis, cellular respiration occurs in animal cells only.

15.  Plants release energy from glucose using photosynthesis.

16.  The products of photosynthesis are the reactants of cellular respiration.

17.  Glycolysis is the processes that takes place in the cytoplasm of a cell.

18.  Glycolysis provides a cell with a net gain of 36 ATP molecules.

19.  The starting molecule for glycolysis is pyruvic acid.

20.  Glycolysis requires ATP to start the process.

21.  Glucose is NOT a product of glycolysis.

22.  NAD + is an electron carrier that plays a role in cellular respiration.

23.  Pyruvic acid is the starting molecule for the Krebs cycle.

24.  The Krebs cycle does NOT occur without the presence of oxygen.

25.  The Krebs cycle produces lactic acid.

26.  The Krebs cycle starts with pyruvic acid and yields lactic acid.

27.  In the presence of oxygen, glycolysis is followed by alcoholic fermentation.

28.  In eukaryotes, electron transport occurs in the outer cell membrane.

29.  NADH and FADH 2 pass high-energy electrons to the electron transport chain.

30.  High-energy electrons that move down the electron transport chain ultimately provide the energy needed to convert ADP molecules into ATP molecules.

31.  The energy of the electrons passing along the electron transport chain is directly used to split water molecules.

32.  Cellular respiration uses 1 molecule of glucose to produce approximately 2 ATP molecules.

33.  Lactic acid fermentation occurs in muscle cells.

34.  The two main types of fermentation are called alcoholic and lactic acid.

35.  The air bubbles and spongy texture of bread are due to lactic acid fermentation.

36.  When microorganisms in milk produce acid under certain conditions, yogurt results because alcoholic fermentation is key in the production of yogurt.

37.  During fermentation, NAD + is regenerated, allowing glycolysis to continue.

38.  The conversion of pyruvic acid into lactic acid requires NADH.

39.  Breathing heavily after running a race is your body’s way of making more citric acid.

40.  When the body needs to exercise for longer than 90 seconds, it generates ATP by carrying out cellular respiration.

41.  The energy needed to win a 1-minute footrace is produced mostly by lactic acid fermentation.
