hi i have a big problem got a practical, the effect of catalase on the rate of reaction on hydrogen peroxide. but i don't know the amount of hydrogen peroxide i should use or the source of enzyme? can anyone help? the source of enzyme cant be liver or potato. thanks S x

The enzyme? Prick your finger and use a drop of blood. The amount of peroxide? IT depends on how you are measuring rate of decomposition. If visual is all, then use about 20 ml.

Dehydrogen catalase is also found in yeast, if you are to chicken to prick your finger.
