This is a great inquiry based lab to get students thinking about the function of enzymes and the factors that influence rate of reaction and enzyme function. The needed supplies are: Catechol (pyrocatechol), potato juice (or filtered puree), distilled water, test tubes, sugar (small amount of sugar water), hot and cold water baths, water with adjusted pH (3, 5, 7, 9, 11). This lab is best suited after having lecture or discussion over enzyme function and ways that enzymes function can be altered such as: pH, temperature, and enzyme concentration.
Your purchase includes the fully accessible Word document so that you can modify it for your classroom. However, I reserve the copyright, as this is a lab included in a book in the process of publication.
