Later, you will have an opportunity to select an enzyme, research its properties and mode of reaction, and then design an experiment to explore its function. The investigation also provides an opportunity for you to apply and review concepts you have studied previously, including the levels of protein structure, energy transfer, abiotic

We will assume that each filter disk is coated with the same amount of catalase (except in the investigation of the effect of enzyme concentration of enzyme activity). LAB PROCEDURE PART A: (Safety: You will be using glass, hot water, acids, and bases. Use caution and wear goggles.) 1. Prepare a beaker or clear cup with H 2 O 2 that is 4 cm

Lab Objectives. At the conclusion of the lab, the student should be able to: define the following terms: metabolism, reactant, product, substrate, enzyme, denature; describe what the active site of an enzyme is (be sure to include information regarding the relationship of the active site to the substrate) The H 2 0 2 formed by peroxisome metabolism is itself toxic, but the organelle contains an enzyme that converts the H 2 0 2 to water (H 2 O) and oxygen (O 2) gas (bubbles). The enzyme studied in this experiment is called “catalase.” Catalase is an enzyme found in nearly all living organisms. Catalase has one of the highest turnover rates of Videos that can help you understand the lab: Learning Objectives: After completing this activity, students will be able to – Determine the household use of Hydrogen Peroxide Recognize different enzymes and their characteristics Compare and contrast the catalase in animal vs. plant cells Explain why temperature and pH would have an effect on enzyme activity […] Investigation 13: Enzyme Activity Notes From the teacher Day 1: Before class: Read Entire Lab and Complete Pre Lab. Pre-Lab: 1.

Essential Question: How do biotic or abiotic factors influence the rates of enzymatic reactions? Objectives: • To understand In this experiment, we will determine the effect that boiling temperatures have on the enzyme catalase. We will compare the gas production with boiled liver versus Liver and other living tissues contain the enzyme catalase. In this lab, you Throughout this investigation you will estimate the rate of the reaction (how rapidly In turn, there are many physical factors that affect how well an enzyme works in a reaction. In this laboratory, you will investigate the effect some of those factors Lab-Header4 The enzyme studied in this experiment is called “catalase. What effects do you think the pH and temperature will have on enzyme activity?

Gautsch1 Lab 6: Enzymes John Gautsch September 24, 2014 Abstract Lab six requires students to observe the effects of pH and enzyme concentration on catecholase activity. Enzymes are organic catalysts that can affect the rate of a chemical reaction depending on the pH level and the concentration of the enzyme.

Light can also break down H 2 O 2 which is why the chemical is sold in dark containers.

Enzyme reacts differently in different environments. The properties of the environment may influence the rate of an enzyme to react. For example, pH, temperature or substrate concentration.

Investigation Lab 13. Introduction: Enzymes act as catalysts of a biological system. This means that they increase the speed of chemical reactions in biological systems by lowering the activation energy needed to start reacting. Depending on the shapes and structures of the enzymes, the function could change drastically.

Online Enzyme Lab Simulation. Purpose/Background: In this investigation you will determine the effects of substrate concentration and pH on the initial rate of an enzyme-catalyzed reaction. You will be testing two separate questions/hypotheses during this virtual simulation.
