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

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature. Materials: 4 test tubes 2 small beakers A dozen filter paper disks Test tube rack Hydrogen peroxide (H2O2) Potato extract Forceps Thermometer Hot plate Large beaker Ice cubes Graduated cylinder Stopwatch Procedure: Step 1 Place 10 mL of potato

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

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

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

of the lab is to see the effects of enzyme concentration on the reaction rate. Part 2: Effect of Substrate Concentration Purpose: The purpose of this part of the lab was to find the effect of substrate concentration on enzyme activity. Part 3: Effect of Temprature Purpose: The purpose of this part of the lab was to determine the effect of temperature on the rate of enzyme activity

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased
