Aerobic versus Anaerobic

1
Aerobic versus Anaerobic

• Robert, Branko, and Greg.

2
Aerobic

• Most cellular respiration is done via this form
  of respiration.
• Produces 36-38 ATP
• Works with Glycolysis

3
Anaerobic

• Respiration with a lack of oxygen
• Produces just 2 ATP
• Also works the Glycolysis.

4
Fermentation

• Extension of Glycolysis
• Alcohol fermentation and Lactic Acid fermentation

5
Alcohol Fermentation

• Ethanol is the resulting product from the
  conversion of pyruvate
• Then converts to acetaldehyde
• NADH adds a hydrogen ion to acetaldehyde to
  change it to ethanol
• the cell is able to regenerate the supply of NAD

6
Lactic Acid Fermentation

• NADH reduces pyruvate directly
• Used in the dairy industry to make cheese and
  yogurt

7
Fermentation and Respiration

• Both yield a net gain of ATP
• Glycolysis is used in both pathways
• NAD is the oxidizing agent
• Fermentation the final electron acceptor is
  either pyruvate or acetaldehyde
• Respiration  the final acceptor is oxygen
• More ATP is made when the citric acid cycle
  oxidizes pyruvate fermentation
