Aerobic & Anaerobic Respiration

• What is the main source of energy for organisms?

  Molecules of glucose
• What is cellular respiration?

  It is an exothermic reaction that transfers energy from glucose.
• What does the term "exothermic" mean in the context of respiration?

  It means that the reaction releases energy.
• Where does aerobic respiration take place in cells?

  In the 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$_6$
• Why is aerobic respiration considered more efficient than anaerobic respiration?

  Because it fully breaks down glucose to release more energy.
• What is the word equation for anaerobic respiration in humans?

  Glucose → Lactic Acid
• What are the two main reasons why anaerobic respiration is less preferred?

  Incomplete breakdown of glucose and lactic acid buildup.
• What is produced during anaerobic respiration in plants and yeast?

  Ethanol and Carbon Dioxide
• What is fermentation in the context of yeast?

  It is the process where glucose is converted to ethanol and carbon dioxide.
• What are the uses of fermentation in industry?

  • Producing carbon dioxide for leavening bread
  • Producing ethanol for beer and wine
• What are the main types of respiration and their characteristics?

  • Aerobic Respiration:
  • Requires oxygen
  • More efficient
  • Takes place in mitochondria
  • Anaerobic Respiration:
  • Occurs without oxygen
  • Less efficient
  • Produces lactic acid (in humans) or ethanol and carbon dioxide (in yeast)
• What is metabolism?

  • The combination of all chemical processes in a living organism
  • Includes reactions that require energy and those that do not
