Aerobic and anaerobic

• What type of reaction is cellular respiration described as?


  Exothermic reaction
• Why is energy transferred during cellular respiration?

  It supplies all the energy needed for living processes
• What are the two types of respiration that can occur in cells?

  Aerobic and anaerobic respiration
• What is the main difference between aerobic and anaerobic respiration?

  Aerobic respiration uses oxygen, while anaerobic respiration does not
• What are the key differences between aerobic and anaerobic respiration?

  • Need for oxygen:
  • Aerobic: Requires oxygen
  • Anaerobic: Does not require oxygen
  • Products:
  • Aerobic: Carbon dioxide and water
  • Anaerobic: Lactic acid (in muscles) or ethanol and carbon dioxide (in yeast)
  • Energy transferred:
  • Aerobic: More energy transferred
  • Anaerobic: Less energy transferred
• What are some reasons organisms need energy?

  For chemical reactions to build larger molecules, movement, and keeping warm
• What is the equation for aerobic respiration?

  glucose + oxygen → carbon dioxide + water
• What are the chemical symbols for glucose, carbon dioxide, and water?

  CH₄O, CO₂, and H₂O
• What is the equation for anaerobic respiration in muscles?

  glucose → lactic acid
• Why is less energy transferred in anaerobic respiration compared to aerobic respiration?

  Because the oxidation of glucose is incomplete in anaerobic respiration
• What is the equation for anaerobic respiration in plants and yeast cells?

  glucose → ethanol + carbon dioxide
• What is fermentation in yeast cells, and why is it important?

  It is anaerobic respiration in yeast and has economic importance in the manufacture of bread and alcoholic drinks
• The glucose produced in photosynthesis may be used for:

  used for respiration

  converted into insoluble starch for storage

  used for fat or oil for storage

  used to produce amino acid for protein synthesis

  used to produce cellulose
