Question

name: michael bagq
station 3: anaerobic respiration
explain 2: cellular respiration stations

1. true or false: anaerobic respiration does not require oxygen.
2. how much energy does it make per 1 glucose molecule? 36 atp
3. where does it occur in the cell?
4. what is the one and only step of anaerobic respiration?
5. what are two types of anaerobic respiration?
6. what helpful hint can help you remember anaerobic respiration?

station 4: types of anaerobic respiration

1. write the equation of lactic acid fermentation. circle the waste product.
2. describe two examples of lactic acid fermentation.
3. write the equation for alcohol fermentation. circle the waste product.
4. describe one example of alcohol fermentation.

conclusion: compare and contract aerobic and anaerobic respiration
aerobic respiration (4 bullets) both (2 bullets) anaerobic respiration (4 bullets)

Explanation:

1. Anaerobic respiration is a process that occurs without oxygen, so the statement "Anaerobic Respiration does NOT require oxygen" is True.
2. Anaerobic respiration (fermentation) produces 2 ATP per glucose molecule, not 36 ATP which is produced in aerobic respiration.
3. Anaerobic respiration occurs in the cytoplasm of the cell.
4. The main step of anaerobic respiration is glycolysis, which breaks down glucose into pyruvate.
5. The two types of anaerobic respiration are lactic - acid fermentation and alcohol fermentation.
6. A helpful hint could be "Anaerobic means without air (oxygen)".

For lactic - acid fermentation:

• Equation: Glucose (C₆H₁₂O₆) → 2 Lactic Acid (C₃H₆O₃). The waste product is lactic acid.
• Examples: Muscle cells during strenuous exercise and bacteria in yogurt production.

For alcohol fermentation:

• Equation: Glucose (C₆H₁₂O₆) → 2 Ethanol (C₂H₅OH) + 2 CO₂. The waste products are ethanol and carbon - dioxide.
• Example: Yeast cells during bread - making or beer - brewing.

For the comparison:

• Aerobic Respiration: Requires oxygen, occurs in mitochondria, produces a large amount of ATP (36 - 38), has multiple steps including glycolysis, Krebs cycle and electron - transport chain.
• Both: Start with glycolysis, produce energy in the form of ATP.
• Anaerobic Respiration: Does not require oxygen, occurs in cytoplasm, produces a small amount of ATP (2), has two main types (lactic - acid and alcohol fermentation).

Answer:

1. True
2. 2 ATP
3. Cytoplasm
4. Glycolysis
5. Lactic - acid fermentation, Alcohol fermentation
6. Anaerobic means without air (oxygen)

For lactic - acid fermentation:

• Equation: Glucose (C₆H₁₂O₆) → 2 Lactic Acid (C₃H₆O₃), waste product: Lactic acid
• Examples: Muscle cells during strenuous exercise, Bacteria in yogurt production

For alcohol fermentation:

• Equation: Glucose (C₆H₁₂O₆) → 2 Ethanol (C₂H₅OH) + 2 CO₂, waste products: Ethanol and CO₂
• Example: Yeast cells during bread - making or beer - brewing

Comparison:

• Aerobic Respiration: Requires oxygen, occurs in mitochondria, produces 36 - 38 ATP, multiple steps (glycolysis, Krebs cycle, electron - transport chain)
• Both: Start with glycolysis, produce ATP
• Anaerobic Respiration: Does not require oxygen, occurs in cytoplasm, produces 2 ATP, two main types (lactic - acid and alcohol fermentation)
