3
Q 1How is fermentation different from cellular
respiration?
4

• A1
• Fermentation does not require oxygen to make ATP.
• Fermentation produces only 2 ATP molecules per
  glucose molecule, while cellular respiration
  produces 28.

5
Q 2Give examples of products that depend on
fermentation in microorganisms.
6

• A2
• Fermentation during exercise produces a waste
  product called lactic acid
• Fermentation in yeast produces alcohol and
  releases carbon dioxide
• Fungi and bacteria produce lactic acid during
  fermentation

7
Q 3 fermentation
8

• A3
• fermentation cellular process of making ATP
  without oxygen

9
Q 4 anaerobic
10

• A 4
• anaerobic without oxygen

11
Q 5How does fermentation in yeast produces ethyl
alcohol? (Drawing)
12

• A5 Fermentation in Yeast

13
Q6How does fermentation makes ATP entirely from
glycolysis?(Drawing)
14

• Fermentation makes ATP entirely from glycolysis,
  the same process that is the first stage of
  cellular respiration. Note in this drawing that
  glycolysis does not use oxygen

When little oxygen is available in muscle cells,
fermentation allows glycolysis to continue.
15
Q 7Describe one example of how fermentation in
microorganisms produces human foods.
16

• A7
• Microbes transform milk into cheese or yogurt
  soybeans into soy sauce cabbage into sauerkraut.

17
Q 8What is the waste product of fermentation in
your muscle cells?
18

• A8
• Lactic acid is the waste product of fermentation
  in your muscle cells.

19
Q 9How is ATP made during fermentation?
20

• A9
• Fermentation makes ATP entirely from glycolysis
  without using oxygen

21
Q 10List four food products made by fermentation.
22

• A10
• Examples of food products made by yeast
  fermentation are
• Beer
• Wine
• Bread
• Examples of food products made by fungi and
  fermentation are
• Cheese and yogurt
• Soy sauce
• Sauerkraut
