Enzymes can accomplish a lot but can they also solve a crime? In this simulation experiment, students will determine the level of the enzyme amylase for two drivers to determine who was responsible for a deadly accident. They‚Äôll use an iodine test to visualize the disappearance of the substrate (starch) and they‚Äôll use a Dinitrosalicylic acid test to visualize the appearance of produce (maltose). A great way to understand enzymatic reactions in a fun and engaging forensic context.
‚Ä¢ Understand the role of enzymes as biological catalysts
‚Ä¢ Determine enzyme activity levels based on two colorimetric tests
‚Ä¢ Observe how enzyme levels affect substrate disappearance & product creation rate
‚Ä¢ Learn forensic analysis procedures that maintain the integrity of the evidence
Instructions, simulated control and driver saliva samples, starch, HCl, Iodine, and detection solutions, transfer pipets, microtiter plates, microtest tubes.
