Anaerobic & Aerobic respiration

    Cards (9)

    • Respiration is the release of energy from sugar molecules such as glucose.
    • Is respiration an exothermic or endothermic reaction?
      Exothermic
    • Which process in plants produces the glucose required for respiration?
      Photosynthesis
    • examples of how cells use the energy from respiration.
      To combine small molecules to make larger molecules
      To break large molecules into smaller molecules
      For muscle contraction
      To maintain our body temperature
      To move substances around the cell
    • What is metabolism?
      The combination of all chemical reactions in an organism
    • What is the word equation for aerobic respiration? 
      Glucose + oxygen ➔ carbon dioxide + water
    • What is glucose converted to during anaerobic respiration in animals?
      Lactic acid
    • word equation for anaerobic respiration in plants and fungi:
      Glucose ➔ ethanol + carbon dioxide
    •  two reasons animals cells prefer aerobic respiration to anaerobic respiration?
      Anaerobic respiration doesn't break down the glucose molecule completely, and so releases less energy than aerobic respiration
      Anaerobic respiration produces lactic acid which can damage cells and leads to an oxygen debt
