Anaerobic Respiration

• What is the word equation for Fermentation?

  A) glucose

  B) ethanol

  C) carbon dioxide

  
• What happens to your muscles during exercise?

  They need to transfer more energy than normal
• How does your body respond to increased energy demand during exercise?

  Your heart and breathing rate increase
• What is anaerobic respiration?

  Energy transfer without oxygen
• What is the word equation for anaerobic respiration?

  glucose -> lactic acid
• What is produced during anaerobic respiration?

  Lactic acid is produced
• Why is lactic acid considered poisonous?

  It causes pain and muscle fatigue
• Why does the body prefer aerobic respiration?

  It produces more ATP per glucose molecule
• What happens when lactic acid builds up in muscle cells?

  It causes pain and stops muscle contraction
• What is oxygen debt?

  Extra oxygen needed to break down lactic acid
• What occurs after you finish exercising?

  You breathe heavily to break down lactic acid
• What is the main consequence of anaerobic respiration?

  Production of lactic acid
• How does aerobic respiration differ from anaerobic respiration?

  Aerobic respiration fully breaks down glucose
• What is the role of glucose in anaerobic respiration?

  It is the source of energy
• Do other organisms perform anaerobic respiration?

  Yes, other organisms perform anaerobic respiration
• Why do animals use anaerobic respiration?

  To transfer energy quickly when needed
• In what situation might an animal respire anaerobically?

  When being chased by a predator
• Where does anaerobic respiration occur in plants?

  In the roots of waterlogged soils
• What products are produced by anaerobic respiration in microorganisms and plant cells?

  Ethanol and carbon dioxide
• What is fermentation in the context of anaerobic respiration?

  It is anaerobic respiration producing ethanol and CO2
• How does anaerobic respiration differ from aerobic respiration?

  Anaerobic respiration occurs without oxygen
• What is the role of glucose in anaerobic respiration?

  It stores energy that is transferred
• What are the key characteristics of anaerobic respiration?

  • Occurs without oxygen
  • Produces ethanol and carbon dioxide in plants and microorganisms
  • Transfers energy from glucose
  • Used by animals in high-energy situations
