"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme
Catalase Which Is Found In The Liver"
Introduction: Enzymes are biological catalysts. They speed up the
chemical reactions which go on inside living things. Without them the reactions
would be so slow that life would grind to a halt. Enzymes work by when a
substrate molecule bumps into a molecule of the right enzyme, it fits into a
depression on the surface of the enzyme molecule. This depression is called the
active site. The reaction then takes place and the molecules of product leave
the active site, freeing it for another substrate molecule.

Hydrogen peroxide is a waste product produced during ...

The temperature of the liver
2. The surface area of the liver
3. The pH of the hydrogen peroxide
4. The concentration of the enzymes

The two variables I am going to look at are temperature and surface area.


Hypothesis: I think that when we test the surface area the bigger the
surface area the quicker the reaction will be. This is because there are more
liver particles that will be exposed to the hydrogen peroxide, therefore the
liver that is ground up will be the quickest reaction.

For temperature it will be the temperature that is forty degrees Celsius
because the enzymes in the liver will not exist after the temperature goes over
forty degrees Celsius. I know this due to previous experiments that I have
carried out. I think the rate of decomposition will double every ten degrees
Celsius that the liver is warmed up, but when the liver goes over forty degrees
Celsius, the rate of decomposition will slow down.

Therefore my hypothesis is that the rate of ...
