Gbengon‚Sennie Microbiology Lab Case study # 5 November 1‚2012 1. What evidence suggests that the young graduate student has contracted what disease? Ans: The signs and symptoms the young graduate student presented‚ show evidence of Lyme disease. 2. What is the environmental pathway for the vector of this disease? Ans: The environmental pathway for the vector of this disease would be a forested habitat. The black-legged tick or the deer tick is the principle vector of this disease (Lyme

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

1. Title: The Process of Determining the Unknown Bacteria #9 Rachel Judecki July 5‚ 2011 2. Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification‚ the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol

The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of

Enzymes in Pineapple Background: Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts‚ enzymes take part in the reaction - that is how they provide an alternative reaction pathway. But they do not undergo permanent changes and so remain unchanged at the end of the reaction. They can only alter the rate of reaction‚ not the position of the equilibrium. Enzymes are usually

For the preparation of the filtrate solution at the beginning of the class our Instructor‚ Marshall Douglas added about four to five strawberries in the blender along with 100 ml of detergent/ enzyme/ salt solution. They were blended until thoroughly homogenized if foaming occurred more detergent solution was added to prevent it. Then the blended solution was poured into a beaker and left to incubate at 60C for 15 minutes. Also‚ the mixture solution was cooled on ice for 5 minutes and filter through

Temperature Affect Enzyme Activity? Introduction As a group‚ we conducted an experiment to see if temperature would affect enzyme activity. We did this because we are studying enzymes and were curious if they would be affected by temperature. We hypothesized that temperature would affect enzyme activity. We believed this because it seemed fitting that something which increased the role or speed of something would be affected by changes in something like temperature. A catalyst is a substance

BIO 211 Lab Section 11 February 15‚ 2012 Effects of Temperature on Enzymatic Activity Abstract Temperature is a measure of kinetic energy. As this movement increases‚ collision rate and intensity‚ and therefore reaction rates‚ increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction
