LAB 9: DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost

Executive Summary This report analyses the costs associated with two of Coffee Beans Inc. products‚ Moana Loa and Malaysian blends based on two different costing methodologies‚ namely the traditional job costing system that the company uses so far and the Activity Based Costing (ABC). ABC provides us with a more detailed and accurate estimation of the real cost of the products and it can serve as the basis for suitable strategic decisions‚ concerning products mix‚ pricing‚ suppliers and market

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

PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating. The turbidity

Summary of Findings 1. Music affects the growth of Mung beans. As established in the experiment and based on the data gathered‚ music has a great effect on the growth of Mung beans. The varying degree of effect is dependent on the type or tempo of music to be played. 2. In general‚ music helps in the growth of plants. It hastens the growth of plants. As we conducted and observed our experiment‚ we noticed that classical music helps the Mung beans’ growth. Plants exposed to rock music grew slower than

Homesickness is the experience of longing for one’s home during a period of absence from it. In “Snapping Beans” by Lisa Parker the idea of homesickness is a described as a young girl and her grandmother snap beans together after she returns from college. Although the snapping of the beans is a very important aspect of the poem the symbolization of a “hickory leaf” is far more important than this simple yet important and homely task. The summer green hickory leaf represents the girl breaking away

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

F. Scott Fitzgerald’s book‚ The Great Gatsby‚ and his short story called The Jelly Bean both give readers an insight to what the 1920’s were about and how times have drastically changed. Fitzgerald utilizes the effects of symbolism‚ irony and foreshadowing through both works to help him get his points across to the readers. The works that Fitzgerald has written showcase the “American Dream” and how wealth and class influence everyone’s decisions and attitudes. By using foreshadowing‚ irony and symbolism
