Bio Lab

Lab 6-Enzymes Purpose: The purpose of this science research laboratoryoratoryoratory is to visitation for enzyme activity, enumerate at enzyme specificity, and how temperature affects enzyme activity. Time need to set this lab: some 3 hours Preparation FIRST: Read the lab in its entirety TWICE before you begin. You impart perform the experiment, write your lab report and allow the answers to the loanitional 4 questions within the textual matter for in force(p) credit on this experiment. Materials: * 3% hydrogen peroxide * a household blender * murphyes (3 average 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 * range of a function * 4 blow over plastic cups * pair of tongs (to change test tubes from boiling water) * 4 coffee cups * cheesecloth to filter the potato s how * a wax pencil or eager beaver marker * a ruler * scale or equaliser * 250 ml graduated cylinder * oven mitt or tongs Preparation Step 1: Research (online) the reaction betwixt 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. abandoned your research, why argon we measuring the height of the bubbles produced to indicate how much enzyme activity has occurred? 2. What product are we specifically observing universe produced? Preparation Step 2: 1. Prepare the potato extract ! (catalase) using the following proficiency: * peel 3 median(a) size potatoes and cut them into quarters * add the potatoes to the blender with 250 mls of tip water to cover the potatoes and blend on high until the potatoes are pureed (blended to a thick naiant or paste) * place a cheesecloth over a container and use the cheesecloth to come up the liquid portion (only) of your potato puree.
