Effect of Temperature on Enzyme Activity of Catalase
A design lab that I did towards the end of last year for biology; our objective was to investigate a factor that affected the enzyme activity of catalase. I chose temperature as my factor of study, and I used two sources of catalase: beef liver and potato catalase. My design lab was given an IB 6 by my biology teacher, so it was only marked internally.
