    Yeah it's hydrogen peroxide. The celery is in the experiment because it contains the catalase.

    • Yep the catalase is in the celery.

    • Substrate is hydrogen peroxide. H2O2

    • The catalse decomposes the hydrogen peroxide to release water and oxygen.

    • The rate of activity is measured by the increase in volume of the bubbles from the washing up liquid.

    • If measuring effect of temp you use different water baths and use a pH buffer to keep that constant

    • If measuring effect of pH you use different pH buffers and the same water bath at constant temp

    Hope that helps.

    No problem :)
    Enzyme experiments are pretty likely apparently! Guy on radio said to focus on them. Good luck with the study! Cramming english myself today =[
