Investigation into the affect of temperature on the action of the enzyme catalyse Aim: To heat the enzyme catalyse (potato slices) to different temperatures to see whether it affects the amount of oxygen produced when it reacts with hydrogen peroxide. Variable: I am going to be changing the temperature that I heat the hydrogen peroxide and potato to before they react. Standards: I am going to be keeping the same: * Size of the potato slices (1cm X 0.5cm X 0.5cm) * Amount of hydrogen peroxide (20ml for each experiment) * Concentration of hydrogen peroxide * Equipment Introduction to enzymes (catalyse): Enzymes are in all living things, they are found in cells and are used to speed up chemical reactions. They are made from protein and are known as 'biological catalysts'. The are two different types of enzyme: builders and breakers. All enzymes are specific to a certain chemical reaction; e.g. catalyse breaks down hydrogen peroxide into...
