    Cards (23)

    • What is the main source of energy for organisms?
      Molecules of glucose
    • What process do we use to release energy from glucose?
      Cellular respiration
    • How is cellular respiration described in terms of energy?
      As an exothermic reaction
    • Where does cellular respiration occur in living cells?
      In mitochondria
    • What happens to glucose molecules during cellular respiration?
      They are broken apart to release energy
    • What is metabolism defined as?
      All chemical processes in a living organism
    • What are the uses of energy in organisms?
      • Building larger molecules from smaller ones
      • Muscular contraction for movement
      • Maintaining body temperature
    • What are the two types of respiration?
      Aerobic and anaerobic respiration
    • When does aerobic respiration occur?
      When there is enough oxygen
    • What is the word equation for aerobic respiration?
      Glucose + oxygencarbon dioxide + water
    • How many molecules of each substance are involved in aerobic respiration?
      Six of each except glucose
    • What is the relationship between aerobic respiration and photosynthesis?
      Aerobic respiration is the opposite of photosynthesis
    • What is anaerobic respiration?
      Respiration without oxygen
    • When do we rely on anaerobic respiration?
      When we can't get enough oxygen
    • What is the word equation for anaerobic respiration in humans?
      Glucoselactic acid
    • Why is anaerobic respiration considered inefficient?
      Incomplete breakdown of glucose occurs
    • What builds up as a result of anaerobic respiration?
      Lactic acid
    • What is anaerobic respiration in plants and yeast?
      Glucose is converted to ethanol and carbon dioxide
    • What is fermentation in yeast used for?
      To produce carbon dioxide and ethanol
    • How is fermentation utilized in industry?
      • Yeast is added to bread for air pockets
      • Yeast is used to make beer and wine
    • What does fermentation produce in bread making?
      Carbon dioxide
