Introduction Chlorite is a general name for a group of magnesium rich hydrous sheet silicates possessing similar structure and chemical composition. Many green rocks owe their color to chlorite and chlorite owes its name to its green color. The Greek word choros, meaning “green,” is the origin of chlorite’s name. Consisting of negatively charged mica-like (2:1) layers regularly alternating with positively charged brucite-like (octahedral) sheets, the basic structure of chlorites allows for various

Introduction Enzymes are biological catalysts. Catalysts are substances that increase the rate of chemical reactions without being used up themselves. Enzymes are also proteins. They all have different and complex shapes that allow smaller molecules to fit into them. The place where these substrate molecules fit is called the active site. The shape of an enzyme can change; its active site may no longer work. It is said the enzyme is denatured. They can be denatured by high temperatures or extremes

reactive. Compare properties of molecules formed from atoms in similar families; for example, H2S versus H2O. Explain what is meant by the electronic structure of atoms. How does knowing the electronic structure of atoms aid chemists in predicting chemical reactions? Periodic Table is designed to help us understand how elements are going to react to each other and also gives us the breakdown of how many atoms are in each element. This chart also helps us to identify metals, liquids, and gases. This

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24, 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in
