  • Different Kinds Of Sugars Into Test Tubes
    670 words
    Enzyme Activity Abstract: The purpose of this experiment is to test the effects of different sugar types with pH and temperatures. We are testing to see if there is a difference in reaction and reaction time when placed into different temperature and pH. We are looking for changes in color, solidity, reaction time, etc. My hypothesis is that at different temperatures and amounts of pH, there will we different reactions. Introduction: The overview of these experiments is to test enzymes and see w...
  • Active Sites And The Rate Of Reaction
    1,080 words
    Enzymes The majority of the reactions that occur in living organisms are enzyme-controlled. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Without enzymes toxins would soon build up and the supply of respiratory substrate would decrease. Enzymes are proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse one enzyme will react with molecules of one substrate. The site of the reaction occurs in an...
  • Tubes After 5 Minutes
    1,451 words
    Lab Report 1 Principles of Biology 1 (BIOL 100) Fall 2001 Gerard Chretien Living cells perform a multitude of chemical reactions very rapidly because of the participation of enzymes. Enzymes are biological catalysts, compounds that speed up a chemical reaction without being used up or altered in the reaction. The material with which the catalysts reacts, called the substrate, is modified during the reaction to form a new product. But because the enzyme itself emerges from the reaction unchanged ...
  • 25 50 Enzyme Activity
    727 words
    Galactosemia Galactosemia is a genetically inherited metabolic disorder. This disorder leaves the disabled with a partial or complete lack of the enzyme Galactose - 1 - Phosphate Uridyl Transferase (GALT). This enzyme is found in the bloodstream and it is used for breaking down the sugar galactose. This disorder comes in two different variations. Though there is more than one type, it is still rare, having only 1 in 80,000 births being affected by the disorder. Classic Galactosemia is the first ...
  • Bond To The Active Site Of Enzymes
    1,008 words
    The structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a micro environment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction, called feedback inhibition. Enzymes are catalytic pro...
  • Enzyme's Activity B Temperature Optimum Most Enzymes
    615 words
    The plot of enzyme activity vs. pH is often 'bell shaped's ince two different amino acid groups of the enzyme are being titrated to different states of ionization at the different pH values. This means that only one of the two possible ionization states of the amino acid side chain is effective in enzyme catalysis - in other words, if an acidic side chain like Glu is involved in catalysis, it probably only works when it is ionized; since Glu side chain acid groups have a pK around pH 5, at pH va...
  • Substrate For The Enzyme
    399 words
    Enzymes are proteins, composed of polypeptide chains and non-protein groups. Their function is to help with the reactions of many cells and molecules by serving as catalysts. A catalyst is a substance that allows the activation energy required for a reaction by forming a temporary association with the molecules that are reacting. During this process, the catalyst itself is not permanently altered in the process, and so it can be used over and over again. Because of catalysts, cells are able to c...
  • Bubble Column In The Enzyme Tube

    Situations That Govern the Pace of an Enzymatic Reaction: Enzyme Concentration, Temperature, and pH Joe Saunders BSC 1010 C; T, R: 11: 50-12: 05 Lab: T: 12: 15-3: 05 INTRODUCTION: An enzyme is any one of many specialized organic substances, composed of polymers of amino acids that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. The word enzyme comes from the Greek phrase en yeast. Many scientists who studied enzymes in the 180...
  • Enzyme Activity
    300 words
    Enzyme are biological catalyst to speed up a specific chemical reaction by providing an alternative pathway with the lower activation energy. Enzyme are protein in nature, it has its own 3-dimension configuration. It works due to presence of active site, a specific region with specific configuration, are able to bind with substrate to form enzyme-substrate complex for reaction. The specific 3-dimension configuration is held by bonds within enzyme. However, heat affect the enzyme activity. Heat p...
  • Concentration Of The Substrate In An Enzyme
    913 words
    The Effect of Concentration of Substrate Starch on the Rate of Reaction of the Enzyme Amylase Brief An enzyme is A compound that catalyzes biochemical reactions. Enzymes are proteins, which act with a given compound (the substrate) to produce a complex, which then forms the products of the reaction. The enzyme itself is unchanged in the reaction; its presence allows the reaction to take place. The names of most enzymes end in -ase, added to the substrate (e.g. lactase) or the reaction (e.g. hydr...
