Grace Doran 10/28/15 Grade 9 Liver Catalase Lab Purpose: The experiment was conducted in order to test whether or not the liver catalase performed different when denatured. Also to test what happens when we change the pH of the reaction. Introduction/ Background Information: A liver is vital in getting rid of toxic substances in the body. It uses enzymes which are proteins that help to complete chemical reactions. The enzyme used in the liver is a catalase enzyme. This enzyme helps to break down hydrogen peroxide (H2O2) into water and oxygen. However enzymes may under extreme heat or pH levels may become denatured and nonfunctional.

Bio104 Laboratory ? Student?s Guide John Jay College, C.U.N.Y Lab #4 ? Page 1 Lab #4: Use of the Microscope; Bacteria and Protists I. The Domains of Life A. There are three major branches, or Domains, on the tree of life: Archaea, Bacteria, and Eukarya. B. It turns out that most of the living things on earth, comprising most of the biomass, are microscopic single-celled species! Today we will look at unicellular examples of two different domains: Bacteria and Eukarya. C. Protists are eukaryotes and most (but not all) are single-celled. However, some of the single-celled protest species can exist in colonies that resemble a multicellular organism, but this is not true
