Through experimental research‚ the percent oxygen of potassium chlorate can be determined using tactics such as stoichiometry‚ a technique used to determine the amount of substances that are in a reaction. Stoichiometry is an efficient way to determine how much of a certain substance is within a certain compound‚ which is used in many practical ways‚ such as pharmaceutical companies using stoichiometry to determine how much of a particular chemical is needed to use within a drug. However‚ within

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

The Science of Catalysts and Catalytic Converters Hosam Sadek February 19th‚ 2013 Catalyst is a term that is used for a chemical agent that selectively increases the rate of a reaction without itself being affected. In the human body‚ enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. These catalysts participate in the reactions‚ but are neither reactants nor products of the reaction they catalyze. The only difference between a catalyzed reaction and

441 Enzyme Lab 10.12.2012 Period 3-4 Purpose/Objective: The purpose/objective of this lab was to see if environmental conditions changed the speed of the reaction. The catalyst being used was the spark (the match). The Chemical reaction being tested was how fast the hydrogen peroxide could turn into water and oxygen. The theory that was being tested was; Enzymes speed up reactions. The facts that I wanted to determine were matches making the chemical reaction happen quicker or not

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

The main catalyst for conflict is fear My father loves to tell me stories about my great grand father‚ who was once a member of the Chinese communist army. I was told that although my great grand father fought many battles against the Japanese‚ he never fought because of his own believe or own hatred‚ the only reason for all his battles is because he was scared. The fear that China will be dominated by another empire and our family might suffer due to the lost of war has caused him to join the war

Homeostasis is the tendency to maintain the internal environment [2]. Hydrogen peroxide is an oxidizing agent that can be decomposed by catalase [11]‚ the liver is able to decompose hydrogen peroxide enzymatically

The purpose of this review paper is to discuss the effect of temperature on enzyme- catalyzed reactions. This is relevant because many diseases can be diagnosed and controlled by the processes of enzyme activity (Worthington 2015). If more information is not found about enzyme activity and how it is affected‚ many diseases may go undiagnosed and uncontrolled. Temperature is a type measurement that does not only consist of heat. It is the measurement of the mean kinetic energy of any group of particles

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Joanne Kathleen Saori T. Suzuki‚ Laurent Santos‚ Val Justin D.M. Tongco* College of Science‚ University of Santo Tomas‚ Manila Philippines Abstract Salivary amylase‚ found in humans‚ is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors‚ such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. However
