A4 - Energy in the Body

• Compare Aerobic and Anaerobic respiration   

  • Aerobic respiration uses oxygen whereas anaerobic does not
  • Aerobic respiration produces CO2 whereas Anaerobic respiration produces lactic acid
• Basal Metabolic Rate

  • The rate at which energy is used
• Aerobic Respiration

  • uses oxygen - produces energy
• Anaerobic Respiration

  • Happens without oxygen - produces lactic acid
• Chemical Energy

  • Carbohydrates are digested into glucose
  • Blood transports glucose and oxygen to cells.​
  • Respiration breaks up chemical bonds in glucose to release the energy
• Anabolic

  • makes large molecules
  • uses small molecules
  • requires energy

  Catabolic

  • breaks down large molecules
  • produce small molecules
  • used in energy production
