Aerobic and Anaerobic Respiration

• What is aerobic respiration?

  Respiration that uses oxygen and yields the most energy.
• Where do most reactions of aerobic respiration occur?

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

  C₆H₁₂O₆ + O₂ → CO₂ + H₂O
• What is anaerobic respiration?

  Respiration that occurs without enough oxygen.
• What is produced during anaerobic respiration in animals?

  Lactic acid.
• What is fermentation in plants and yeast cells?

  Glucose is converted to ethanol and carbon dioxide.
• What type of reaction is respiration?


  Exothermic as energy is transferred to the surroundings
• When does anaerobic respiration occur?


  When there’s not enough oxygen, only used as a last resort and the oxidation of glucose is incomplete
• Equation for aerobic respiration

  C6H12O6 + 6O2 → 6CO2 + 6H2O
• Symbol for glucose

  C6H12O6
• Word equation for aerobic respiration 


  Glucose + oxygen —-> carbon dioxide and water
• What is anaerobic respiration called in plants And yeast?


  fermentation
• equation for anaerobic equation

  Glucose —> lactic acid
• Equation for fermentation 


  glucose → ethanol + carbon dioxide
• What is the fermentation reacted used to make?

  Bread and alcoholic drinks
• What is respiration?

  Respiration is a chemical reaction that releases energy from glucose.
• What is the difference between anaerobic and aerobic respiration?

  Anaerobic respiration occurs without oxygen, while aerobic respiration occurs in the presence of oxygen.
• What is fermentation?

  Fermentation is anaerobic respiration in microorganisms.
• What are the two types of respiration?

  • Aerobic respiration: occurs in the presence of oxygen.
  • Anaerobic respiration: occurs without oxygen.
• What is the scientific name for breathing?

  The scientific name for breathing is ventilation.
• Why is respiration essential for cells?

  Respiration releases energy stored in glucose, which is vital for cell survival.
• In which part of the cell does aerobic respiration occur?

  Aerobic respiration occurs in the mitochondria.
• Which cells have more mitochondria?

  Cells that need more energy, such as sperm cells and muscle cells, have more mitochondria.
• What is the equation for anaerobic respiration in humans?

  The equation is glucose → lactic acid.
• What happens during vigorous exercise regarding respiration?

  During vigorous exercise, anaerobic respiration occurs due to insufficient oxygen for aerobic respiration.
• What is lactic acid's effect on muscles?

  Lactic acid builds up in muscles, causing pain and tiredness, which can lead to cramp.
• What is EPOC?

  EPOC stands for excess post-exercise oxygen consumption.
• What happens to lactic acid after vigorous exercise?

  Lactic acid reacts with oxygen to form carbon dioxide and water, releasing energy.
• What is the equation for fermentation in yeast?

  The equation is glucose → ethanol + carbon dioxide.
• How does fermentation benefit bread and beer production?

  Fermentation produces ethanol and carbon dioxide, which makes bread rise and gives beer its bubbles.
• What happens to ethanol when bread is baked?

  Ethanol is evaporated away when bread is baked.
