Enzyme Activity
Configure & Price
IS.3713
Students will learn the nature and specificity of enzyme-catalyzed reactions. Students will then use an extract of turnips to examine the reaction between hydrogen peroxide and the enzyme peroxidase while testing one or more factors that influence the rate of enzyme reactions. In this lab students will develop data collection strategies and analyze their results.
