Aerobic + Anaerobic respiration

• What is respiration primarily used for in organisms?

  To release energy from glucose
• What type of reaction is cellular respiration?

  Exothermic reaction
• What does cellular respiration involve?

  Breaking apart glucose molecules
• What is the key point about energy in respiration?

  Energy is transferred, not created
• What is aerobic respiration?

  Respiration with enough oxygen
• Where does aerobic respiration take place?

  In mitochondria
• What is the word equation for aerobic respiration?

  Glucose + oxygen → carbon dioxide + water
• What is the chemical formula for glucose?

  C$_6$H$_{12}$O$_6$
• What is anaerobic respiration?

  Respiration without oxygen
• When do humans perform anaerobic respiration?

  When sprinting and oxygen is insufficient
• What is the word equation for anaerobic respiration in humans?

  Glucose → lactic acid
• Why is anaerobic respiration considered inefficient?

  Glucose is only partially broken down
• What is a toxic byproduct of anaerobic respiration?

  Lactic acid
• What is anaerobic respiration in plants and yeast called?

  Fermentation
• What is the word equation for anaerobic respiration in yeast?

  Glucose → ethanol + carbon dioxide
• How is fermentation used in industry?

  To make bread, beer, and wine
• What are the key differences between aerobic and anaerobic respiration?

  • Aerobic respiration requires oxygen; anaerobic does not.
  • Aerobic is more efficient; anaerobic is less efficient.
  • Byproducts of aerobic are carbon dioxide and water; anaerobic produces lactic acid or ethanol and carbon dioxide.
• How does energy from respiration support bodily functions?

  • Builds larger molecules (e.g., proteins)
  • Fuels muscular contractions for movement
  • Maintains body temperature in cold environments
• What role does fermentation play in food production?

  • Produces carbon dioxide for leavening bread.
  • Generates ethanol for alcoholic beverages.
  • Utilizes yeast in various fermentation processes.
• What are the implications of using anaerobic respiration in humans?

  • Less energy is produced due to partial breakdown of glucose.
  • Lactic acid accumulation can lead to muscle fatigue.
  • Anaerobic respiration is a temporary solution during intense exercise.
