Autumn 2003 Experiment To Investigate The Effect Of Concentration On An Enzyme Based Reaction Aim: To investigate the effect of either enzyme or substrate concentration on the rate of decomposition of hydrogen peroxide using catalase enzyme. Introduction: (information obtained from "OCR Biology 1", "Advanced Biology" & "Hutchinson Dictionary of Science") An enzyme is a protein molecule that speeds up chemical reactions in all living things. Without enzymes, these reactions would occur too slowly or not at all, and no life would be possible. Enzymes, for example, are needed for respiration to occur. Enzyme molecules function by altering other molecules, known as the substrate, to form a new product. They combine with the substrate molecules to form a complex molecular structure in which chemical reactions take place before the enzyme, which remains unchanged, separates from the product of the reaction. There have now been over seven hundred different enzymes identified by scientists, which...
