The reactions and Results of Using Enzyme Turnip Root Peroxidase Lab results from: Andrew Compton‚ Mickey. Results published 9/29/2012. TA: In this series of laboratory experiments‚ my lab partner and I were to conduct an experiment about the oxidation rate of the enzyme peroxidase in the presence of its substrate guiacol. Also we used other substrates‚ such as hydroxylamine an enzyme inhibitor‚ to observe the weather the reaction rate was slowed down‚ sped up‚ or stopped reactions all together

Background: This lab involves the testing and measuring of water potential. Water potential (ψ) is the tendency of water to diffuse from one region to another. It measures the free energy available in water to do work. Pure water has a water potential of 0 (kpa--unit?). Water will move from an area of higher water potential to an area of lower water potential. Several factors‚ including temperature‚ pressure (ψp) and solute concentration (ψs) contribute to water potential. (citation-lab) The equation

Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ‚K3 [Fe (C2O4)3].3H2O. Introduction: Ferrous ammonium sulfate‚ Fe(NH4)2(SO4)2.6H2O is dissolved in a slightly acid solution‚ excess oxalic acid‚ H2C2O4‚ is added and the following reaction takes place: Fe(NH4)2(SO4)2.6H2O + H2C3O4

balloon Bar Graph: Discussion Questions: 9) My prediction had been that the test tube with 10% of sucrose inside of it would make the most amount of carbon dioxide. My hypothesis was correct‚ and the size was gradually increasing throughout the lab. At the end it was the biggest‚ so after 1440 minutes‚ the 10% test tube was the only solution that had visible bubbles of carbon dioxide. After 1440 minutes there were no carbon

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

she recently discovered. As part of her visit she brought several supplies‚ so that my class could watch an experiment of the drug taking action in the stomach. The experiment didn’t go as planned. It exploded and nearly killed Ms.Gura. Now as her Bio-Med class we were subjected to find out whether it was an accident or attempted murder. After the incident we were instructed to remember what we saw during the explosive experiment. Each observation was written into our notebooks for recording purposes

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential
