The Effect of Temperature on the Rate of an Enzyme Catalysed Reaction

Aim: To find the effect of temperature on enzymes, using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories, …

…out that, as the temperature increases, so does the catalase activity, as it does not take as long to move the same distance, up to a certain point ( °C) where the activity ceases altogether. I found that the optimum for a catalase is at °C. This is where the greatest number of collisions takes place between the enzyme and the substrate and therefore the highest rate of reaction is.
