Enzyme Investigations

Investigating Enzyme Activity

• By measuring how fast a product appears 
  • The enzyme catalase breaks down hydrogen peroxide into oxygen and water
  • Collect and measure oxygen in a set time
  • Pipette to add set amount of hydrogen peroxide to boiling tube
  • Put tube in a water bath at 10`c
  • Add a source of catalase (e.g. 1cm^3 of potato to tube and attach bung
  • Record how much is oxygen produced - repeat three…
