scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

Diagnosis: Physical symptoms of liver trauma include blood loss‚ tenderness of the region‚ peritoneal irritation and its guarding. Haemodynamically stable patients with suspected live injury should be investigated for imaging studies. Focused Assessment with Sonography in Trauma (FAST) is usually useful for both blunt and penetrating trauma. FAST has sensitivity from 75-94 % and specificity from 97-100 % for intra-abdominal fluid in trauma patients. FAST cannot distinguish between laceration and

environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in the hydrogen

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

Does Temperature Affect Enzyme Activity? Introduction As a group‚ we conducted an experiment to see if temperature would affect enzyme activity. We did this because we are studying enzymes and were curious if they would be affected by temperature. We hypothesized that temperature would affect enzyme activity. We believed this because it seemed fitting that something which increased the role or speed of something would be affected by changes in something like temperature. A catalyst is a substance

pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong
