The discovery of restriction enzymes took place over about a decade and is accredited to biologists Warner Arber, Hamilton Smith and Daniel Nathans. Although they were not working together directly, they followed each other’s work closely and made invaluable contributions to the discovery and understanding of restriction enzymes in rapid succession. They were on the verge of a breakthrough that would revolutionize the analysis and manipulation of genetics, spawning invaluable technology that is still

Observing Enzyme Catalysis Purpose: • Procedure A (Testing Enzyme Activity)- How do different types of extreme temperatures affect enzyme activity? • Procedure B (Establishing a Baseline)- How much peroxide is needed to establish a baseline for a 1.5% solution? • Procedure C (Rate of Hydrogen Peroxide Spontaneous Decomposition)- How do oxygen and water affect the spontaneous decomposition of hydrogen peroxide? • Procedure D (Rate of Hydrogen Peroxide Decomposition by Enzyme Catalysis)-How does different

I. Science Fair Question How does an enzyme convert sucrose into glucose and how we digest glucose from different foods? II. Background Research The idea of this project is to test drinks and foods by dipping a urinalysis test strip into them and see how much sugar is in each drink and food. This project will measure two sugars, glucose and sucrose in different foods. It can help prove that too much sugar is not healthy and how our bodies digest them. The important terms that will

Introduction Enzymes are an important aspect of many physiological processes because they act as catalysts to speed up reaction rates. Some metabolic reactions have competitive and non-competitive inhibitors that can hinder reaction rates. Competitive inhibitors target the active site of an enzyme, resulting in an equal Vmax, but different Km. Noncompetitive inhibitors, on the other hand, bind to an allosteric site and change the shape of the active site, resulting in the same Km and a lower Vmax

of Starch Hydrolysis in a Porcine Pancreas Introduction: Our body uses various different types of molecules that work together in order to keep us functioning. One of these molecules is called amylase. Amylase is an enzyme that breaks up the glucose chains in starch into maltose. Enzymes work to speed up a reaction by lowering the activation energy needed for the reaction to occur. There are three different types of amylase: α-amylase, β-amylase, and γ-amylase. α-Amylase is commonly found in saliva

The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as

Discuss the structure and function of enzymes: a. Describe the structure of an enzyme as a protein. Describe the resulting enzyme structures that are a result of protein folding. The structure of an enzyme as protein has a primary, secondary, tertiary, and sometimes quaternary structure. The primary structure of an enzyme, like any protein, is the order of its amino acids. The secondary structure involves alpha helices and beta pleated sheets. Alpha helices are a coil that is formed by hydrogen bonding

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein, which is capable of starting a chemical reaction, which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives, grows, or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Comparing Free to Immobilised Amylase Enzyme in Its Catalysis Rate Method: First of all, the Immobilised enzymes need to be made. The method used to create these immobilised enzymes would be Micro encapsulation. This means that the enzyme used, in this experiment being Amylase, is encapsulated inside Sodium alginate. The enzyme was believed to act quickly, so the enzyme would have to be slightly diluted in order to get a good range of results. !0cm³ of Amylase will

Laboratory 7: Environmental Effects on Enzyme Activity BI-185-03 BY Charlie Kane 10/24/17 Abstract During this experiment we tested the effects that specific environmental conditions have on the enzyme, peroxidase. Through this experiment we developed an understanding of enzymes and their functions. By exposing the enzymes to different environments, we observed a changed in their activity. In order for us to measure these changes we used the technique of spectrophotometry, meaning we used
