The effect of different substrate concentrations on the rate of reaction. My aim is to investigate what happens when concentration of Hydrogen Peroxide is changed and how it affects the rate of reaction when it is broken down by the enzyme catalase (H2O2 --> 2H2O + O2) Scientific knowledge. Enzymes are biological catalysts, regulating the rate at which chemical reactions take place without the enzyme being altered in the process. Enzymes bind temporarily to one or more of the substrate molecules of the reaction they catalyse. Enzymes work by lowering the activation energy required for a reaction to proceed. In order to do so, and enzyme molecule must unite - even if very briefly - with the substrate molecule(s). Enzymes are able to do this because an area of their structure matches to the substrate. This area is called the active site and is complementary in shape, charge and hydrophobic/hydrophilic areas. The...
