Cards (27)

  • What should you be able to describe at the end of this video?
    Aerobic and anaerobic respiration
  • Why is energy important in biology?
    For movement, warmth, and chemical reactions
  • What is the process that supplies energy in cells?
    Cellular respiration
  • What type of reaction is respiration?
    Exothermic reaction
  • Where does respiration take place?
    In all living cells
  • What is the word equation for aerobic respiration?
    Glucose + OxygenCarbon Dioxide + Water + Energy
  • What does aerobic respiration produce?
    Carbon dioxide and water
  • Why does aerobic respiration release a great deal of energy?
    Because glucose is fully oxidized
  • What is the chemical symbol for glucose?
    C<sub>6</sub>H<sub>12</sub>O<sub>6</sub>
  • What is the chemical symbol for oxygen?
    O<sub>2</sub>
  • What is the chemical symbol for carbon dioxide?
    CO<sub>2</sub>
  • What is the chemical symbol for water?
    H<sub>2</sub>O
  • What happens when there is not enough oxygen for aerobic respiration?
    Cells carry out anaerobic respiration
  • What do muscle cells convert glucose to during anaerobic respiration?
    Lactic acid
  • What is a key fact about anaerobic respiration?
    It does not require any oxygen
  • How does anaerobic respiration compare to aerobic respiration in terms of energy release?
    It releases much less energy
  • In which cells can anaerobic respiration take place?
    Muscle, plant, and yeast cells
  • What is the reaction for anaerobic respiration in yeast?
    Glucose → Ethanol + Carbon Dioxide
  • What is anaerobic respiration in yeast called?
    Fermentation
  • What is produced by fermentation in yeast?
    Ethanol and carbon dioxide
  • How is fermentation useful in making alcoholic drinks?
    It produces ethanol
  • How does fermentation help in bread making?
    Carbon dioxide creates bubbles in dough
  • What are the key differences between aerobic and anaerobic respiration?
    • Aerobic respiration requires oxygen; anaerobic does not.
    • Aerobic produces carbon dioxide and water; anaerobic produces lactic acid or ethanol and carbon dioxide.
    • Aerobic releases a lot of energy; anaerobic releases much less energy.
  • What are the main products of aerobic respiration?
    • Carbon dioxide
    • Water
    • Energy
  • What are the main products of anaerobic respiration in muscles?
    • Lactic acid
    • Energy
  • What are the main products of anaerobic respiration in yeast?
    • Ethanol
    • Carbon dioxide
    • Energy
  • What are the uses of fermentation in food production?
    • Producing alcoholic beverages
