Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This is very

Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

Enzymes are biological catalysts that operate at the temperatures‚ pressures‚ and moderate pH values found in living organisms. They help in a faster chemical reaction in our human body. Besides this‚ enzymes also play a huge role in various industries. The following paragraphs will talk about how various enzymes are used in various industries : The Dairy Industry and Medical Industry. In the dairy industry‚ the enzyme Protease is used widely.

Equipment | Justification | 100 cm3 burette | I needed to accurately measure out large quantities of hydrogen peroxide (90 cm3 and 150 cm3). The 100 cm3 burette is a precise instrument and would allow me to measure out the hydrogen peroxide by filling it fewer times than I would need to with 50 cm3 burette. | 50 cm3 burette | I needed to repeatedly measure out small volumes of solutions A–I.
