FORMATIVE ASSESSMENT ITEM: Chemistry of Life Practical Investigation Term 1
Task: Investigation of a Factor Affecting Enzyme ActionAspects Assessed: D DCP CE MS Introduction:Thousands of enzymes are found in living cells. In addition to making life possible, many enzymes have numerous applications that affect our daily lives in other ways such as food processing, clinical diagnoses, sewage treatment, and the textile industry. In this activity you will investigate how a particular factor influences the action of an enzyme. Conditions: Students are NOT required to design an experiment. Experimental design has been provided for you to use instead. You are however required to submit a Risk Assessment for the investigation. Students are to work independently. However, you will need to collect raw data from 4 other students to make the 6 trials. The final version is to be submitted to TURNITIN and then class teacher. A journal will need to be included as part of the final submission. Time Allowed: 4 weeksDue Dates Task Out first lesson week1, term 1, 2013Risk Ass Due: last Lesson week 2, Term 1, 2013Final: First lesson week 6, Term 1, 2013Procedure: Your task is to investigate the effect of temperature on the activity of enzyme catalase found in beef liver. Use the experimental design and the BioLab Guide provided to assist with your report write up. Safety Considerations: You must have the risk assessment checked before continuing. NOTE: For this task you are required to submit a journal which documents your progress. You are also required to include photographs which display the techniques you used in the experimental
