Biology “Enzyme Activities” Introduction: Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level‚ a cell is really a little bag full of chemical reactions that are made possible by enzymes (Brain). Laboratory

Enzymes (pron.: /ˈɛnzaɪmz/) are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts‚ greatly accelerating both the rate and specificity of metabolic reactions‚ from the digestion of food to the synthesis of DNA. Most enzymes are proteins‚ although some catalytic RNA molecules have been identified. Enzymes adopt a specific three-dimensional structure‚ and may employ organic (e.g. biotin) and inorganic (e

Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical properties

Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

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

Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

Does regulated hunting help preserve wildlife? The first step to answering this question is to define “regulated hunting” itself. The Merriam-Webster Dictionary defines regulate as: “to control or supervise something by means of rules‚” and defines hunting as: “the activity of hunting wild animals or game‚ especially for food or sport.” Through this‚ one can gather that regulated hunting would mean something along the lines of: “to control or supervise the activity of hunting wild animals or game

Abstract: Enzymes are specific-type proteins that act as a catalyst by lowering the activation energy of a reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2)
