Other questions in this quiz

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

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

3. Why does anaerobic respiration happen?

  • Muscles can't be supplied with Oxygen quickly enough
  • Water is being lost too quickly from sweat and breathing
  • So muscles can produce more than using Aerobic respiration

4. What does lactic acid cause?

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

5. What is produced during anaerobic respiration?

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