"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 respiration.
Hydrogen peroxide is produced to kill off dangerous bacteria. The hydrogen
peroxide is broken down, so that it can not be dangerous anymore, into water
(which is given off when you perspire) and into oxygen (which can be given off
when you exhale).

A toxin like hydrogen peroxide must be broken down because if it is kept
in the body for too long it can react with cell walls and damage them or break
them down.

The variables that affect the decomposition of hydrogen peroxide are:
1. 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 ...
