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
  • Muscle contraction
  • Maintain a constant body temperature (in animals)
  • Used to build up larger molecules from small molecules (e.g Proteins from amino acids)

3. Why does anaerobic respiration happen?

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

4. What is Oxygen debt?

  • The amount of oxygen that must flow through muscles to oxidise and remove the lactic acid the has built up
  • The amount of oxygen needed to oxidise the CO2 produced in Aerobic respiration
  • The amount of Oxygen needed to normalise the Oxygen levels in the blood after exercise

5. What does lactic acid cause?

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