2) Boil 2 of the cubes of potato for 5 minutes. How can you tell that catalase has been added to hydrogen peroxide? 7. I believe the Carolina transformation kit instructions say to use the plasmid within a month. Each simulated test tube contains the same enzyme solution. In turn, there are many physical factors that affect how well an enzyme works in a reaction.

Similarly, you can follow up this experiment by having students designing their own experiment to test one of these factors. Sketch the graph of enzyme function and temperature. Enzyme Activity: With 3ml H 2 O 2 and 3ml H 2 O in each tube, add 1 drop of enzyme suspension. Catalase has a molecular weight of approximately 240,000 daltons and contains 4 polypeptide chains, each composed of more than 500 amino acid monomers. : Preview the questions on the left side. 5 5-6-16 Procedure 2: Effect of Enzyme Concentration on Activity Enzyme activity is also affected by the concentration of the enzyme, the reactants, and the products. Be sure to decide on the following: LABORATORY REPORT Activity: Enzyme Activity Name: Natalie Banc Instructor: Elizabeth Kraske Date: 09. Enzymes are macromolecular biological catalysts. What do you observe at low temperature, medium temperature and high temperature? 8. Fill the beakers with enough of the appropriate solution to cover your bags (refer to the above table). 5 mL of the solutions from tubes ‘A’ and ‘B’ and placing this into tubes A2 and B2 (at 5 mins), A3 and B3 (at 10 mins), etc. Lab 6 - Enzymes 1 Effect of Enzyme Concentration on Catalase Activity Enzyme Concentration 5 drops 10 drops 20 drops Average Max Rate (%O2 per minute) 0.

In this lab we will make up mock cells using a material called dialysis tubing. What is the dependent variable in this experiment? _ c. Quickly memorize the terms, phrases and much more. The purpose of this lab is to determine if changes in temperature will have an effect on the activity of an enzyme. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. what takes place in each step of the diagram: What 2 environmental conditions can affect the activity of an enzyme? _& _ Use the 2 graphs below to answer Questions 5-6. What three factors impact enzyme function? Enzymes and Temperature. In particular, this lab explores the properties of the enzyme lactase, its product, glucose, and the difference in reaction between sucrose and lactose.

9 Lab 7 - Enzymes II Use data to graph results Effect of Temperature on Catalase Activity Temperature 0° 25° (RT) 37° 50° 85° Average Max Rate (% O2 per minute 0. Hydrogen peroxide is the substrate for catalase.
