2.5 Enzymes
This Catalase lab should be familiar to IGCSE students. Read through the outline, maybe carry out a preliminary practical. Think about the limitations of this method and how it could be improved. As a class (or in groups) redesign the lab to use better more sophisticated equipment before carrying it out.
This Catalase Lab from Access Excellence has good ideas for both creating different enzyme concentration and how to the measure the dependent variable.
Invertase is an enzyme present in yeast, amongst other organisms, this simple protocol (source unknown - please contact if you do know) serves as a preliminary lab and hence as a basis for full (D, DCP and CE) investigations.
The one enzyme that plays a part in browning reaction in fruit and vegetables that occurs when they are bruised and damaged is catecholase. This simple lab outline using potatoes as a source of catecholase can be used by itself or as a basis for full (D, DCP and CE) investigations.
Protease action on powdered milk is a simple outline for practising data processing, analysis, conclusion and evaluation skills. There's lots of opportunity for valuable qualitative observations and for possible improvements. I strongly suggest formulating a hypothesis as it will inform both your data processing and your conclusion and evaluation.
