Investigating Enzymes: Phosphatase Enzymes in Plants
One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A standard protocol which is used to extract phosphatase enzymes from plants, including a method to calculate the rate of reaction. Investigations using this protocol can be found on the Science & Plants for Schools website. Phosphatases are enzymes widespread in plants easily extracted from germinating seeds. The pink substrate phenolphthalein phosphate (PPP) can be used to estimate the amount of enzymatic activity, and investigations can be carried out under differing pH and temperatures. Students have the opportunity to use colorimeters in this practical.
The resource is suitable for use for A level, Scottish Highers and IB.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
