Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases until the optimum pH

Enzyme action is the simple mechanism by which enzymes catalyse chemical reactions. This begins with the binding of the substrate to the active site on the enzyme. The binding of the substrate to the enzyme causes changes in the distribution of electrons in the chemical bonds of the substrate. This then causes the reactions that lead to the formation of products that are then released from the enzyme surface to regenerate the enzyme for another reaction cycle. The active site has a unique shape that
