One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A simple yet accurate protocol looking at the results of the enzyme catalase. Catalase is a widespread enzyme, protecting the cell from toxic effects of hydrogen peroxide by catalysing its decomposition into molecular oxygen and water. This reaction can be carried out on a very small scale, in a centrifuge tube. 

The resource is suitable for A level, Scottish Highers and IB.
