Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Study Guide for Unit V Energy and Enzymes. What is cellular work? Why must living things utilize energy with maximum efficiency? Define energy. Why do living things need a constant input of energy? Where does all energy in the biosphere originate? Define kinetic and potential energy. (Give biological examples). What are the two laws of thermodynamics? Give examples. What is entropy and what is the law of entropy? How do living things resist the law of entropy? Give biological examples. Define

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

Science investigation Aim: To try to see if the temperature affects the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme‚ Enzymes‚ also called catalysts‚ are in living things and there are thousand of them. Enzymes break down food by the active site on the Enzyme forming a chemical bond with a substrate and then water attacks the substrate until it is hydrolysed (split in 2). Equipment: Boiling

head‚ occasionally working on individual poems for many years. Long lived like most of his family‚ Alfred Lord Tennyson died on October 6‚ 1892‚ at the age of 83. The two poems that I will be talking about today will be Break‚ Break‚ Break and Ulysses. “Break‚ Break‚ Break” is a lyrical poem which centers on Tennyson’s grief over the death of his closest friend Arthur Hallam. Throughout the poem Tennyson grieves for his loss of his friend. Nature does not stop to mourn for the loss of anyone

of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

Immobilized Enzyme Immobilized Enzyme * Enzymes which are attached to small bead made of alginate are called immobilized enzyme * However‚ whatever the nature of an immobilized enzyme‚ it must comprise two essential functions‚ namely the non-catalytic functions (NCF) that are designed to aid separation and the catalytic functions (CF) that are designed to convert the target compounds within the time and space desired * Immobilized enzymes might meet the increasing demand by manufacturers

Do you like paying $3.78 for a gallon of gasoline? Well‚ as of May 16‚ 2008 that is the national average. You wake up knowing you need to fill the tank and the hair stands up on the back of your neck as you think of how much more the price has increased over night. It doesn’t have to be that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to
