Respiration

• Aerobic respiration

  • Oxygen + glucose -> carbon dioxide + water + energy
  • 6O2 + C6H12O6 -> 6CO2 + 6H2O + 38ATP
  • Occours in mitochondria
• Where do animals get oxygen from

  Alveoli
• Where do plants get oxygen from?

  Stomata
• Where do animals get glucose from?

  Small intestine
• Where do plants get glucose from?

  Photosynthesis
• Is aerobic respiration endothermic or exothermic?

  Exothermic
• Mitochondria

  • Inner membrane folded to increase surface area
  • Enzymes needed for respiration in inner membrane
• Anaerobic respiration in animals:

  • Occours in cytoplasm
  • Glucose -> lactic acid + 2ATP
  • Produces less energy than aerobic respiration
• Why is lactic acid bad for you?

  It is toxic
• Anaerobic respiration in plants and fungi:

  • Glucose -> ethanol + Carbon Dioxide+ 2ATP
