Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did

This purpose of the lab was to observe and compare the reactivity of the elements within groups and the reactivity of the groups themselves. The elements of each group were reacted with fire‚ acid (HCl or HNO3)‚ or in deionized water. According to the observations‚ the most reactive group was the alkali metals. Since the alkali metals are in group 1‚ they only have one valence electron and can easily lose this electron. As you move towards the right of the periodic table‚ the number of electrons

Diagnostic Urinalysis Lab Introduction/Background Today’s lab exercise is about diagnostic Urinalysis. Urine reflects the many chemical components found in blood. This test is a good measure of health of endocrine system‚ kidneys‚ and urinary tract. Artificial urine samples are used for today’s lab thank goodness. The test that this lab is mostly focused on is called “dipstick” urinalysis test where students will analyze the chemical composition of urine by dipping the chemical indicator stick or

Yeast Lab Report Guidelines 1. Lab reports are to be computer-generated and double-spaced. All sections of the report must be written in paragraph form. 2. Do not use encyclopedias (Internet or otherwise)‚ dictionaries ((Internet or otherwise)‚ or personal web pages as sources for the report‚ this includes Wikipedia. You may use a textbook‚ lab manual‚ and/or article(s) in a published journal. You can find journal articles by going to the library website: http://www.lib.clemson.edu/ and selecting

Determination of Gatifloxacin and Ornidazole in Tablet Dosage Forms by High-Performance Thin-Layer Chromatography 43 A simple and sensitive high-performance thin-layer chromatography method has been developed for the quantitative estimation of gatifloxacin and ornidazole in its combined dosage forms. Gatifloxacin and ornidazole were chromatographed on silica Gel 60 F254 TLC plate using n-butanol: methanol: ammonia (6 M) (8:1:1.5 v/v) as the mobile phase and scanned at 302 nm using a Camag TLC Scanner

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the

optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic acid (ACC)5‚ which is the rate-limiting step in ethylene biosynthesis. ACC is then converted to ethylene by ACC oxidase (ACO)‚ a member

percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid catalyzed aspirin‚ we saw an average of 55.0% percent yield and an average 42.2% percent error. The Ka value for sulphuric acid is 1.0 x 10³ while the Ka value for phosphoric acid is 7.1 x 10⁻³. Knowing that the Ka value denotes the acidity of
