Other questions in this quiz

2. Which of these is NOT a use of the energy released in respiration?

  • Diffusion of Oxygen and CO2, and Osmosis
  • Used to build up larger molecules from small molecules (e.g Proteins from amino acids)
  • Muscle contraction
  • Maintain a constant body temperature (in animals)

3. What is produced during anaerobic respiration?

  • lactic acid and water (+energy)
  • amino acids and CO2 (+energy)
  • lactic acid (+energy)
  • CO2 and water (+energy)

4. What does lactic acid cause?

  • Muscles to increase in size
  • muscle fatigue (muscles stop contracting efficiently and hurt)
  • increased rate of digestion
  • Neutralisation of water in muscles

5. What percent of energy is released by Anaerobic compared to aerobic respiration?

  • 5%
  • 50%
  • 500%
  • 0.5%
