It Is A Laboratory Essay On An Experiment We Did Over Enzymes And The Effects Of The Parameters On Enzymes.

1436 words - 6 pages

ABSTRACT Environmental Parameters on Enzyme Activity. Joey McSloy, Functional Biology, Texas State University, San Marcos, TX 78666.Environmental parameters may affect the enzyme activity rate. We investigated the effects from four different parameters (substrate concentration, ph level, temperature level, and salt concentration. Each parameter was tested in different ways to determine the effects of enzyme activity. Each parameter tested and had an optimum level where the enzyme activity was at its peak (neutral ph 7, high substrate concentration, 3% salinity rate, and 11 degrees Celsius) INTRO The research conducted was preformed to determine the effects of different parameters of enzyme activity. By doing this experiment we hope to find the best conditions for enzyme activity. Enzyme activity can vary greatly depending on the conditions in which the reactions occur. By changing these conditions we hope to get a better knowledge and understanding of the parameters that will limit enzyme activity.The first of the four parameters tested was substrate concentration and how it affects enzyme activity. The null hypothesis in this experiment was that there will be no change on the enzyme activity as a result in the change of substrate concentration. The alternative hypothesis was that changing substrate concentration would effect the enzyme activity rate. The experiment preformed for substrate concentration would indefinitely show the optimum level of substrate concentration. The peroxide substrate will interact with the turnip peroxidase, and it will effect the enzyme activity because it binds to the enzyme, reacts and then is released.The second parameter was the pH level and how it effects the enzyme activity. The null hypothesis in this experiment was that there will be no change on the enzyme activity as a result in the change of the pH level. The alternative hypothesis was that changing the pH level would effect the activity of the enzyme. The pH level is simply a measure of how acidic or basic it is and in this experiment we can determine what pH would be the optimum level for the enzyme activity.The third parameter was the concentration of salt and how it effects the enzyme activity. The null hypothesis in this experiment was that there will be no change on the enzyme activity as a result in the change of the salt concentration. The alternative hypothesis was that changing the salt concentration would effect the activity of the enzyme. The salt concentration itself will act upon the enzyme (turnip peroxidase) itself and affect the speed of the reaction.The fourth parameter was the Temperature and how is effected the enzyme activity. The null hypothesis in this experiment was that there will be no change on the enzyme activity as a result in the change of the temperature. The alternative hypothesis was that changing the temperature would effect the enzyme activity rate. The temperature changing should effect the activity of the enzyme because...

This causes both sides of the ocean to bulge as illustrated in the diagram above causing 2 high tides, about 12h and 25 minutes apart.Relatively the same idea applies to the effects of the Sun on Earth, though the centrifugal force on the near side of earth is downward, not upward. As it turns out, the force of the sun is about half the force of the moon. We get the high spring tides when the Earth, Sun and Moon are in a straight

Biological washing powders contain a range of hydrolysing enzymes such as amylases which break down starch stains, lipases which break down lipid stains into fatty acids and glycerol, cellulases which break down the ends of damaged cotton fibres in order to remove "fuzz" produced when cotton is washed, and proteases are also

1027 words - 4 pages substrate. The site of the reaction occurs in an area on the surface of the protein called the active site. Since the active site for all molecules of one enzyme will be made up of the same arrangement of amino acids, it has a highly specific shape. Generally, there is only one active site on each enzyme molecule and only one type of substrate molecule will fit into it. Chymotrypsin and trypsin both catalyse the hydrolysis of peptide bonds but due

The Advantages of using Enzymes in Biotechnology

1159 words - 5 pages take place more readily. An advantage of using enzymes in biotechnology is that we can manufacture enzymes with specific properties or characteristics that are essential in a particular problemThe problem with carrying out enzyme-catalysed reactions with the enzyme in the solution is that it leads to enzymes going to waste. There was also difficulty in removing the enzymes from the end products and even more difficulties when purifying the

Variables, such as temperature increases or decreases, can instigate dramatic effects on the enzyme and its intended function.The enzyme has a three-dimensional structure that is specific for the acceptance of a unique like enzyme and when fused together they form a new complex product. The enzyme then returns to its original state, upon which time recycles this process of fusion with its specific substrate.The experiment
