Aerobic and Anaerobic Respiration

• Aerobic Respiration:

  • Respiration with oxygen
  • Happen inside mitochondria

  glucose + oxygen - > carbon dioxide + water
• Anaerobic Respiration:

  • Respiration without oxygen
  • Does not transfer as much energy as aerobic - glucose is not fully oxidised
  • Useful in emergencies

  glucose - > lactic acid
• Anaerobic respiration in plants and yeast:

  • Plant and yeast respire without oxygen but they produce ethanol and carbon dioxide
  • Anaerobic respiration in yeast cells is fermentation
  • Fermentation is of great value as it is used to make bread and alcholoic drinks
  • In bread making, carbon dioxide makes bread rise
  • In making alcohol, it's the fermation that makes the alcohol

  glucose - > ethanol + carbon dioxide
• • Oxidation of glucose is incomplete in anaerobic respiration
  • So, less energy is transferred thn in aerobic respiration
