P12 - Investigate The Effect Of Temperature On Catalase Activity

Question 1

Describe The Process Of Investigating The Effects Of Temperature On Catalase Activity
(5 Points)

Answer 1

~ Set up a series of water baths at different temperatures and boiling tubes containing 5cm3 of hydrogen peroxide solution.

~ Place boiling tubes in water baths, at different temperatures, for 10 mins.

~ Add a sample of catalase solution to a boiling tube and place bung on the boiling tube.

~ Watch the measuring cylinder, to see how much oxygen is produced at 10 second intervals, over 1 minute.

~ Repeat at different temperatures and concentrations.
