Quick Science Fair Question - Testing Enzyme Reaction Rates

[lifeaintchess]

Hi! I was hoping someone could answer a quick question I had about science fair... I had talked to my teacher about doing a project where I test the reaction rate of enzymes in turkey giblets (see which chunk of the turkey has fastest/lowest reaction rates) but we didn't go into a lot of detail when we were talking about it. To use the hydrogen peroxide/disk way of testing reaction rates, could I just grind up/mash up the giblets and use the liquid in place of catalase solution? Would that work at all? I think that's what he was saying, but we talked really briefly about it. If that wouldn't work, is there anything of high-school level difficulty that would?

That may work. Liquid you get after grinding/mashing is - after all - solution of everything that was soluble and was present in the giblets. It can be tricky as it is solution of everything - so not only of the enzyme you are interested in, but also many different ones, they can interfere. But the idea is definitely worth a try.
