Description

In this experiment, the catalase activity in yeast is analysed at different temperatures. When the enzyme catalase comes into contact with its substrate, hydrogen peroxide, it begins to break it down into water and oxygen.

The speed of the reaction is measured by the time it takes for the catalase from yeast to convert the available amount of hydrogen peroxide into oxygen. The faster the reaction, the shorter this period.
