Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

measure the extent of enzyme reaction on given substrates by means of color change. The reaction followed is given below: Tyrosinase³ Enzyme Pyrocatechol Hydroxyquinone Oxidation/Reduction Pink ³ Brown E+S + [ES] = E+P Enzyme Reaction Hypothesis: If there is an increase in enzyme concentration‚ an increase in reaction temperature‚ or an increase in buffer pH‚ then greater intensity in a given reaction will be experienced

Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β- amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

Science IA Rough Draft The Effect of Temperature on The Activity of The Enzyme Catalase Introductions: Enzmyes are proteins that catalyze chemical reactions. All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide"

introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study of enzymes has

Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

ENZYME COFACTORS AND INHIBITORS 1. DESCRIBE THE GENERAL ROLE OF COFACTORS IN ENZYME ACTIVITY. Some chemicals enhance an enzyme’s activity‚ which is what cofactors function to do. They are a non-protein component of an enzyme and may be organic molecules (called coenzymes) or inorganic ions. 2. (A) NAME FOUR HEAVY METALS THAT ARE TOXIC TO HUMANS. Four heavy metals that are toxic to humans are: 1. Cadmium (Cd) 2. Lead (Pb) 3. Mercury (Hg) 4. Arsenic (As) (B) EXPLAIN IN GENERAL TERMS WHY THESE
