Lab Assessment Questions & Answers 1. Define why change control management is relevant to security operations in an organization. Change control is a precision arrangement of managing every change made to a system. This is to ensure that no unneeded changes are done‚ that every change is documented‚ and that no service is disrupted unless absolutely necessary‚ and that all resources efficiently used. 2. What type of access control system uses security labels? A LBA C Label Base Access

Effects of Substrate Concentration‚ Reaction Time and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID#: 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L‚ Section 017 Wednesday‚ 9:30am-12:20pm‚ 151 November 09‚ 2011 A living system controls its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and specific order. Almost all enzymes are proteins‚ except for ribozymes. The chain of amino

The experimental results were different from the hypothesis because while the enzyme appeared to not work as well‚ I expected a more significant change. Most of the time‚ there was only a millimeter of difference of the foam between the two samples while I expected a greater difference such as 10 millimeters. Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water

Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

This experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments

Investigating the effect of enzyme concentration on the rate of an enzyme-catalysed reaction. James Moore Conclusion: For the conclusion we see that in fact the hypothesis is correct. When independent variable increases so does the dependent variable. As the amount of enzyme concentration increases so will

Abstract The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius.

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

the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive. What are Enzymes? Enzymes are found in the
