Bio Lab

Lab 6-Enzymes Purpose: The purpose of this science testing groundoratory is to running play for enzyme activity, enumerate at enzyme specificity, and how temperature affects enzyme activity. Time need to coif this lab: some 3 hours Preparation FIRST: Read the lab in its entirety TWICE before you begin. You will perform the experiment, write your lab report and admit the answers to the loanitional 4 questions deep down the textual matter for proficient credit on this experiment. Materials: * 3% hydrogen peroxide * a household blender * murphyes (3 modal(a) size potatoes, that ar peeled and quartered) * lean water * 8 test tubes * 8 transfer pipets * sugar packets * salt * a small saucepan * a refrigerator with a freezer * kitchen range * 4 blow over plastic cups * pair of tongs (to call in test tubes from boiling water) * 4 coffee cups * cheesecloth to filter the potato sublimate * a wax pencil or live wire marker * a ruler * scale or parallelism * 250 ml graduated cylinder * oven mitt or tongs Preparation Step 1: Research (online) the reaction amongst catalase and hydrogen peroxide and be familiar with the reactants, products, and enzyme. You will include the overall reaction in your lab report for this experiment.

We will measure enzyme activity by mensuration the height of the bubbles produced. Questions 1. presumption your research, why ar we measuring the height of the bubbles produced to indicate how lots enzyme activity has occurred? 2. What product are we specifically ob serving organism produced? Preparation Step! 2: 1. Prepare the potato extract (catalase) using the following proficiency: * peel 3 long suit size potatoes and cut them into quarters * add the potatoes to the blender with 250 mls of tumble water to cover the potatoes and blend on high until the potatoes are pureed (blended to a thick smooth-spoken or paste) * place a cheesecloth over a container and use the cheesecloth to come up the liquid portion (only) of your potato puree.
