aerobic and anaerobic respiration

• Respiration is the release of energy from sugar molecules such as glucose
• respiration is exothermic
• metabolism:

  • The combination of all chemical reactions in an organism 
• word equation for aerobic respiration:

  • glucose + oxygen -> carbon dioxide + water
•  glucose is converted into lactic acid during anaerobic respiration
• anaerobic respiration in plants and fungi:

  • Glucose → Ethanol + Carbon dioxide
• What are the two reasons animals cells prefer aerobic respiration to anaerobic respiration?

  • more energy output
  • prevention of lactic acid build-up
• use of glucose in animals:

  • respiration - aerobic and anaerobic
  • store as glycogen
