Respiration

• Aerobic respiration


  Respiration using oxygen
• Aerobic respiration


  • Goes on all the time in plants and animals
  • Most of the reactions happen inside mitochondria
• Aerobic respiration

  1. glucose + oxygen

  2. carbon dioxide + water
• Anaerobic respiration


  Incomplete breakdown of glucose when there is not enough oxygen
• Anaerobic respiration does not transfer anywhere near as much energy as aerobic respiration
• The oxidation of glucose is not complete in anaerobic respiration
• Anaerobic respiration in plants and yeast cells

  1. glucose

  2. ethanol + carbon dioxide
• Fermentation


  Anaerobic respiration in yeast cells
• Uses of fermentation

  • Making bread
  • Making alcoholic drinks (beer and wine)
