Aerobic Respiration vs. Fermentation
2
Aerobic Respiration

• Aerobic means with oxygen
• Oxygen is required for these processes to occur
  it is the final acceptor of electrons
• 36 additional ATP can be produced
• Includes the Krebs cycle the electron transport
  chain.

3
Fermentation (Anaerobic Respiration)

• Anaerobic means without oxygen.
• Oxygen is not required for these reactions to
  occur another substance is the final acceptor of
  electrons
• No additional ATP is produced.
