4.4 Bioenergetics

• Aerobic Respiration - The process of releasing energy from glucose using oxygen.
• Aerobic respiration equation - glucose + oxygen -> carbon dioxide + water + energy
• Aerobic respiration take place in the cytoplasm and mitrocondria
• Aerobic respiration produces a large amount of energy
• Anaerobic respiration (animal cells) - the process of releasing energy from glucose without oxygen, producing lactic acid
• Anaerobic respiration (animal cells) equation - glucose --> lactic acid + energy
• Anaerobic respiration (animal cells) produces a small amount of energy
• Anaerobic respiration (animal cells) is common in muscle cells during intense excercise
• Anaerobic respiration (alcoholic fermentation) - the process of converting glucose into ethanol and carbon dioxide without the presence of oxygen
• Anaerobic respiration (alcoholic fermentation) - glucose -> ethanol + carbon dioxide
• Comparing Aerobic vs Anaerobic Respiration:

  Oxygen requirement - Aerobic respiration requires oxygen, whilst anaerobic respiration does not.

  End Products - aerobic respiration produces carbon dioxide and water, anaerobic respiration produces lactic acid or ethanol + carbon dioxide

  Energy Yield: aerobic respiration creates a much larger amount of energy than anaerobic respiration

  Efficiancy: aerobic respiration is much more efficient
