    Inhibition of YADH Aim The aim of the experiment is to investigate the inhibitory effects of acetaldehyde. Principle: According to Palmer (1991)‚ “an inhibitor is a substance decreases the rate of an enzyme catalysed reaction”. The binding of inhibitors normally affects the activity of an enzyme. Enzyme inhibition studies are important because most poisons and drugs achieve their effects by inhibiting cell. Enzyme inhibition is also an important phenomenon in the cell metabolism because allows

    down starch in solutions that are increasing in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the
