An Investigation of Enzyme Activity Through Testing for Changes in Starch Solution with the Addition of Enzyme Amylase
Enzyme Activity Aim: To investigate enzyme activity by testing for changes in a starch solution when the enzyme amylase is added and how this reaction is affected by heat, pH, ratios etc. Background of Enzymes Enzymes are biological catalysts produced by living cells. Like all catalysts, they greatly speed up al...
A Look at the Enzyme Catalase and How It Works in the Human Body
Hypothesis Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing together...
An Investigation of the Effect of Substrate Concentrations on the Rate of the Decomposition of Hydrogen Peroxide When Catalyzed by the Enzyme Catalase
For this investigation I have been asked to investigate (by experimentation) the effect of substrate concentrations on the rate of the decomposition of hydrogen peroxide when catalyzed by the enzyme catalase. This is part of our work on the function of enzymes, how they work and the effects of conditions on how they w...
An Introduction to the Importance of the Enzyme Activity
Lab Report 1 for Enzyme Activity The purpose of the following experiments is to better understand the use of enzymes as a means to create complex molecules that are otherwise challenging or nearly impossible to make through abiotic processes. The following experiment is to assess the activity of acid phosphatase as an enzy...
Enzyme Action: Testing Catalase Activity
Enzyme Action: Testing Catalase Activity Introduction: Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specifi...

A Look at Affirmative Action in Employment
Affirmative action is the term used to describe a variety of steps taken in employment, contracting and education to increase diversity or rectify discrimination. Affirmative Action in Employment: Affirmative action programs in employment can consist of posting and publicizing job notices in locations that are likely to be...
A Chemical Experiment Involving the Catalase Enzyme and Hydrogen Peroxide
Hypothesis Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing toget...
An Experiment on the Isolation and Purification of the Enzyme Alkaline Phosphotase from Cells of the Bacterium Escherichia Coli
The goal of this experiment is to isolate and purify the enzyme Alkaline Phosphotase from cells of the bacterium Escherichia coli. Alkaline Phosphotase is an enzyme that catalyzes the hydrolysis of phosphate monoesters in nature. A slew of different techniques are used in this set of experiments in order to purify the prote...
An Experiment to Test the Effects of pH on Enzymes
Ryan Ohalleran 10/23/11 Bio Lab In the third exercise we worked in groups of fours to test the effects of pH on enzyme activity. The test subject was the liver cell, which was exposed to pH levels of two, eight, and fourteen, along with water and hydrogen peroxide. My hypothesis for this experiment was the lower th...
A Study of the Activity of the Enzyme Catalase
Introduction In this experiment, I will be studying the activity of the enzyme catalase. Catalase breaks down of Hydrogen peroxide H2O2 into water H2O and oxygen O2. catalase 2H2O2 2H2O O2 catalase Hydrogen peroxide water oxygen Enzymes are biological catalysts. They are made up of protein....
An Analysis of the Enzyme Amylase and the Investigation Into the Factors Affecting its Activity
Investigation on factors affecting the enzyme Amylase Aim: An investigation into the factors affecting the activity of the enzyme Amylase - Planning Prediction: I predict that as the temperature increases, the speed of the reaction will increase. When a particular temperature is reached, I believe the rate of reaction...
The Description of an Enzyme and How It Works in the Body
Define Enzyme A globular protein functioning as a biological catalyst Define active site The site on surface of enzyme to which substrate or substrates bind Describe the lock and key model In the same way as a key fits a lock very precisely, so the substrate fits accurately into the active site of the enzyme molecule. The...
A Discussion on the Impact of Concentration of Substrate Hydrogen Peroxide on Enzyme Catalase
INTRODUCTION The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------*2H2O O2. It is one of the fastest known enzymes and its turnover number is 6 million, which means the number of substrate molecules which one molecule of the enzyme turns to prod...
An Introduction to Telomere and Telomerase
An Introduction To Telomere and Telomerase The telomere-telomerase hypothesis of aging and cancer is based on the findings that most human tumors have telomerase activity while normal human somatic cells do not. An emerging hypothesis is that the up regulation or reexpression of telomerase is a critical event re...
An Experiment to Determine the Effects of an Enzyme's Concentration on the Breakdown of Starch
For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down...
How Enzymes Work in the Human Body
Hypothesis Hydrogen peroxide will breakdown to oxygen and water in the presence of Catalase. The reaction will increase with increasing enzyme concentration when molecules of hydrogen peroxide are freely available. However, when molecules of the substrate are in short supply, the increase in rate of reaction is limited an...
The Effects of Temperature on Enzyme Catalase
Aim: To investigate the effect of temperature on the enzyme catalase. Prediction: Using my existing scientific knowledge, I predict that as I raise the temperature to 30, 35, and 40, this is where we will see the greatest reaction. I predict this because enzymes are designed to react best at the body temperatures of the a...

Affirmative Action Law and Its Application in the American Legal System
To write about Affirmative Action, one has to understand the meaning of it. What is Affirmative Action? Affirmative Action is also as known positive or legal discrimination. The law was put in place in place in the United States for the first time in early 1960’s. The definition for Affirmative Action is: “ the practi...
An Argument Against Affirmative Action in the Workplace
A very prevalent topic these days, whether in the workplace or at a college, is affirmative action. Many people are Pro-affirmative action, and many are against. I,for one, am against it. I believe that affirmative action creates a lower standard to those of minority groups, and encourages them to think they deserve what th...
Examining Affirmative Actions on Documents
Personal Statement One area of our winter class study that really interested me was affirmative action. As a woman from a minority background affirmative action is a factor that impacts and affects my life, and therefore is the area I would like to examine for my final paper. I will, or at least plan on focusing on race ba...
The Advantages of Affirmative Action Programs

There are thousands of examples of situations where people of color, white women, and working class women and men of all races who were previously excluded from jobs or educational opportunities, or were denied opportunities once admitted, have gained access through affirmative action. When t...
The Role and Influence of Affirmative Action in the United States
Just 20 years ago, in most states a woman could not sign an apartment lease, get a credit rating, or apply for a loan unless her husband or a male relative agreed to share the responsibility. Similarly, a 1965 study found that fifty one percent of men though women were "temperamentally unfit for management." There...
