Catalase is found in living tissues, but a good reaction can be observed when using chicken livers. In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. Light can also break down H 2 O 2 which is why the chemical is sold in dark containers. To begin this investigation, you will focus on the enzyme catalase obtained from beef liver extract, one of numerous sources of this enzyme.

This may be very impractical for many classrooms. If heat blocks or water  Lab Turnip Peroxidase Peroxidase enzymes are widely distributed in plants and animals, including bacteria, in this guided-inquiry laboratory investigation. Alternative Experiment #1 to AP Investigation #13.

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 

This is inconsistent with how catalase works because the enzyme denatures in solutions above a pH of 7.
This experiment was conducted within a range of pH 3 to pH of 11, so this investigation is valid. An Investigation of Catalase/Hydrogen Peroxide Enzymatic Kinetics Lauren Perryman With Racquel Robinson, Kimberly Roberts, Halie Choate Abstract Catalase is an enzyme that breaks down hydrogen peroxide into water and gaseous oxygen. The research outlined in this paper investigated this property of Discussion In this lab we found that the boiling test tubes remained clear throughout the entire time interval.

Enzyme Lab is designed for use with students at the level of senior high school and older. This simulation develops skills in applying the scientific method to 

In this lab, students will use yeast as a source of catalase. Students will change the temperature of the substrate, hydrogen peroxide, and measure oxygen production with a gas pressure sensor. As oxygen is produced, gas pressure will increase. In this lab, you will study an enzyme that is found in the cells of many living tissues.

For over 30 years Enzyme Research Laboratories has been manufacturing and distributing a variety of enzymes and cofactors used in basic coagulation research. By constantly striving for products of utmost quality, ERL has earned the trust of coagulation research communities worldwide. Microsoft Word - 1-6 Virtual Enzyme Lab.docx Created Date: 3/8/2015 12:49:04 PM Enzyme + Substrate --> Enzyme-Substrate Complex --> Enzyme + Product(s) + ΔG For this investigation the specific reaction is as follows: Catalase + Hydrogen Peroxide --> Complex --> Catalase + Water + Oxygen 2H 2 O 2 → 2H 2 O + O 2 (gas) Notice that the catalase is present at the start and end of the reaction. Like all catalysts, enzymes are Buffers and Enzyme Inhibitor can be stored at room temperature. x. Enzyme should be stored atr20 qC.

This lab fits in Chapter 2 (Chemistry of Life) of Freshman Biology with enzyme activity. Overview. In this lab, students will use yeast as a source of catalase. Students will change the temperature of the substrate, hydrogen peroxide, and measure oxygen production with a gas pressure sensor. As oxygen is produced, gas pressure will increase.
