AP Biology enzyme lab. Substrate = hydrogen peroxide. Enzyme = Potato. students should test the reaction between potato extract and peroxide with 6 serial dilutions of potato enzyme solution also test denaturation of enzyme with heat and vinegar. Include background information on enzyme substrate complex, materials list, procedure, data charts, graphing, analysis questions, and conclusion questions
This resource outlines a comprehensive laboratory investigation into enzyme kinetics, focusing on the catalase enzyme found in potato extract and its reaction with hydrogen peroxide. The objective is for students to analyze how variables such as enzyme concentration, temperature, and pH affect catalase activity. Students will be guided through experimental procedures including a serial dilution of potato extract for varying enzyme concentrations, measuring the production of oxygen gas as an indicator of enzyme activity, and testing denaturation effects caused by extreme temperature and acidity. Key concepts discussed include the Induced Fit model of enzyme action, the mechanism of denaturation, and the relationship between enzyme concentration and reaction rates. The document also includes safety protocols, materials lists, data collection methods, and analysis questions that encourage deeper understanding of enzyme function and experimental accuracy.
