4 Which of the following is released during cellular respiration?
oxygen air energy lactic acid

5 Cellular respiration uses one molecule of glucose to produce
2 ATP molecules. 34 ATP molecules. 36 ATP molecules. 38 ATP molecules.

6 What is the correct equation for cellular respiration?
6O2 + C6 H12 O CO2 + 6H2O + Energy 6O2 + C6 H12O6 + Energy ® 6CO2 + 6H2O 6CO2 + 6H2O ® 6O2 + C6 H12O6 + Energy 6CO2 + 6H2O + Energy ® 6O2 + C6 H12O6

7 Cellular respiration releases energy by breaking down
food molecules. ATP. carbon dioxide. water.

8 What are the reactants in the equation for cellular respiration?
oxygen and lactic acid carbon dioxide and water glucose and oxygen water and glucose

9 Which of these is a product of cellular respiration?
oxygen water glucose all of the above

10 Which of these processes takes place in the cytoplasm of a cell?
glycolysis electron transport Krebs cycle all of the above

11 Glycolysis provides a cell with a net gain of
2 ATP molecules. 4 ATP molecules. 18 ATP molecules. 36 ATP molecules.

12 The starting molecule for glycolysis is
ADP. pyruvic acid. citric acid. glucose.

13 Glycolysis requires an energy input. oxygen.
hours to produce many ATP molecules. NADP+.

14 Which of the following is NOT a product of glycolysis?
NADH pyruvic acid ATP glucose

15 Which of the following acts as an electron carrier in cellular respiration?
NAD+ pyruvic acid ADP ATP

16 Lactic acid fermentation occurs in
bread dough. any environment containing oxygen. muscle cells. mitochondria.

17 The two main types of fermentation are called
alcoholic and aerobic. aerobic and anaerobic. alcoholic and lactic acid. lactic acid and anaerobic.

18 One cause of muscle soreness is
alcoholic fermentation. glycolysis. lactic acid fermentation. the Krebs cycle.

19 Which process is used to produce beer and wine?
lactic acid fermentation glycolysis alcoholic fermentation the Krebs cycle

20 Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt? the Krebs cycle photosynthesis alcoholic fermentation lactic acid fermentation

21 During lactic acid fermentation,
NAD+ is regenerated, allowing glycolysis to continue. glucose is split into three pyruvic acid molecules. oxygen is required. 3 ATP molecules are produced.

22 The conversion of pyruvic acid into lactic acid requires
alcohol. oxygen. ATP. NADH.

23 In the presence of oxygen, glycolysis is followed by
lactic acid fermentation. alcoholic fermentation. photosynthesis. the Krebs cycle.

24 Cellular respiration is called an aerobic process because it requires
light. exercise. oxygen. glucose.

25 Which organism is NOT likely to carry out cellular respiration?
tree mushroom anaerobic bacterium tiger

26 The starting molecule for the Krebs cycle is
glucose. NADH. pyruvic acid. coenzyme A.

27 The Krebs cycle does not occur if
oxygen is present. fermentation occurs. glycolysis occurs. carbon dioxide is present.

28 The Krebs cycle produces
oxygen. lactic acid. electron carriers. glucose.

29 The Krebs cycle starts with
lactic acid and yields carbon dioxide. glucose and yields 32 ATPs. pyruvic acid and yields lactic acid or alcohol. pyruvic acid and yields carbon dioxide.

30 The electron transport chain can be found in
prokaryotes. animals. plants. all of the above

31 In eukaryotes, electron transport occurs in the
mitochondria. chloroplasts. cell membrane. cytoplasm.

32 Which of the following passes high-energy electrons into the electron transport chain?
NADH and FADH2 ATP and ADP citric acid acetyl – CoA

33 Each pair of high-energy electrons that moves down the electron transport chain provides enough energy to transport water molecules across the membrane. convert 3 ADP molecules into 3 ATP molecules. convert carbon dioxide into water molecules. break glucose into pyruvic acid.

34 The energy of the electrons passing along the electron transport chain is used to make
lactic acid. citric acid. alcohol. ATP.

35 Breathing heavily after running a race is your body’s way of
making more citric acid. repaying an oxygen debt. restarting glycolysis. recharging the electron transport chain.

36 When the body needs to exercise for longer than 90 seconds, it generates ATP by carrying out
lactic acid fermentation. alcoholic fermentation. cellular respiration. glycolysis.

37 If you want to control your weight, how long should you exercise aerobically each time that you exercise? at least 90 seconds less than 15 minutes 15 to 20 minutes more than 20 minutes

38 The energy needed to win a 2-minute footrace is produced mostly by
lactic acid fermentation. cellular respiration. using up stores of ATP. breaking down fats.

39 Which statement mainly explains why even well-conditioned athletes have to pace themselves for athletic events that last several hours? Lactic acid fermentation can cause muscle soreness. Heavy breathing is needed to get rid of lactic acid. Cellular respiration releases energy more slowly than fermentation does. all of the above

40 All of the following are sources of energy during exercise EXCEPT
stored ATP. alcoholic fermentation. lactic acid fermentation. cellular respiration.

41 Which process does NOT release energy from glucose?
glycolysis photosynthesis fermentation cellular respiration

42 How are cellular respiration and photosynthesis almost opposite processes?
Photosynthesis releases energy, and cellular respiration stores energy. Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back. all of the above

43 Photosynthesis is to chloroplasts as cellular respiration is to
cytoplasm. mitochondria. nuclei.

44 Plants cannot release energy from glucose using
glycolysis. photosynthesis. the Krebs cycle. cellular respiration.

45 The products of photosynthesis are the
products of cellular respiration. reactants of cellular respiration. products of glycolysis. reactants of fermentation.

46 Cellular respiration releases energy by breaking down glucose in the presence of carbon dioxide.
True False

47 If an animal cell stops carrying out cellular respiration, it will die.
True False

48 The products of glycolysis are 2 ATP, 2 NADH, and 2 pyruvic acid molecules.
True False

49 Either cellular respiration or fermentation can be used to release energy, depending on the presence of carbohydrates. True False

50 The pathway labeled A in the figure is called glycolysis.
True False

51 If carbon dioxide is not present, the pathway labeled C in the figure usually will not occur.
True False

52 The Krebs cycle releases energy in the form of ATP.
True False

53 Without the Krebs cycle, the electron transport chain would produce very few ATPs.
True False

54 carry electrons from the Krebs cycle to the electron transport chain.
True False

55 In prokaryotes, the electron transport chain is located in the inner membrane of the mitochondria.
True False

56 If you swim aerobically for 30 minutes, your body has probably started to break down stored molecules, such as fats, for energy. True False

57 The first few seconds of intense exercise use up the cell’s stores of fat.
True False

58 During the course of a long race, a person’s muscle cells will use both cellular respiration and lactic acid fermentation to produce ATP. True False

59 The reactants of photosynthesis are the same as the reactants of cellular respiration.
True False

60 During photosynthesis, energy is stored in the form of fats.
True False
