THE EFFECT OF TEMPERATURE VARIATION ON THE RATE OF AN ENZYME REACTION Aim: The aim of the experiment is to determine the effect of temperature variation on the rate of an enzyme reaction. We choose hydrogen peroxide as substrate, and catalyse as the enzyme. The latter ingredient is contained in potatoes. In fact, equally sized pieces of potato are involved in the experiment. The following equation predicts the outcome of the reaction between the mentioned reagents: Hydrogen peroxide + catalyse = water + oxygen We measure the rate of reaction by observing the amount of oxygen given off. List of equipment: The apparatus employed in experiment consists of the following items: * Beakers * Thermometer: to measure the temperature of the substrate * Stop clock * Delivery tube: the oxygen given off will travel through this tube * Potato: enzyme catalyse is contained in the potato * Hydrogen peroxide: substrate * Bunsen burner: to heat up the hydrogen peroxide at the...
