Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

reaction. Life would not exist without the presence of enzymes (Phillips‚ 2017). Through chemical reactions‚ this energy is created and is controlled by a catalyst‚ enzymes. Enzymes are known as proteins that are produced in living cells that speed up the metabolic processes of an organism. These catalysts speed up these reactions by decreasing the activation energy‚ how much energy is needed for a chemical reaction to happen (WBC‚ 2015). An enzyme-substrate complex forms when a substrate attaches to

Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize

The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

When you are notified that a user’s workstation or system is acting strangely and log files indicate system compromise‚ what is the first thing you should do to the workstation or system and why? a. Disconnect from the network via unplugging the network interface and pull the power cord. Through doing this you can isolate the damage to the areas that it is located without the chances of it uploading data or changing the system during

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

In this lab we tested the effect of temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower
