    Submitted

  17. Enzyme Lab

    Will changing the state of the enzyme lipase before usage (freezing and boiling), affect the reaction rate when added to the substrate milk?

    Submitted

  18. Rate of Photosynthesis IA

    Experiment measuring rate of photosynthesis

  19. Digestion of starch lab

    Aim: to investigate the action of the enzyme amylase on starch

    Updated

  20. 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.

    Submitted
