Enzyme Investigation Aim: To see the effects of changing the surface area of potato tubes on the decomposition of hydrogen peroxide and the subsequent release of oxygen gas by the naturally occurring enzyme catalyse. Equipment: Hydrogen peroxide 200ml beaker 50ml conical flask Delivery tube Clamp Potato Cork Borer size 4 Burette Prediction: I predict that the larger the surface area of the potato the more hydrogen peroxide will be exposed to the potatoes surface, therefore making the reaction take place faster, giving off more oxygen in the same amount of time. So when the surface are of the potato has doubled I believe the oxygen level would have doubled also. But the smaller the surface area, the less oxygen given off. Background Research: Enzymes are biological catalysts. They speed up the chemical reactions, which go on inside living things. Enzymes are extremely efficient at doing their job. Hydrogen peroxide is a very poisonous so it must be got rid of quickly. Under the...
