Anaerobic Respiration Lab Aim: To identify the products of anaerobic respiration in yeast Apparatus and Materials: boiling tubes‚ delivery tube‚ bungs‚ sugar‚ yeast‚ lime water‚ liquid paraffin‚ Bunsen burner Procedure: Water was first boiled in the boiling tube. A small amount of sugar was then dissolved into the boiled water‚ which was allowed to cool. A little bit of yeast was added then stirred. Apparatus was set up as shown in Figure 4. A layer of liquid paraffin was added to the surface

Name: Fabiola Gonzales ID#: 810004692 Lab Partner: Onecia Alexander Date: Friday 23rd October 2015 Theory: Arginase is an enzyme with the E.C. number 3.5.3.1 (Worthington 2015). This details it as a hydrolase enzyme that catalyses the cleavage of bonds through the addition of water. For this experiment‚ we pay close attention to the reaction where arginase catalyses the hydrolysis of arginine to ornithine and urea. This reaction is a part of the urea cycle and occurs in mammalian livers and sometimes

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

Genetic transformation of Escherichia coli with pGLO (Adapted from: Biotechnology Explorer: Bacterial Transformation: The pGLO System. Instructors Guide. BIO-RAD). Objectives a. To understand one of the most commonly used techniques for introducing DNA into E. coli cells and its use in molecular cloning. b. To become familiar with the concept of using green fluorescent protein (GFP) as a molecular tag for studying gene expression in bacteria and other organisms.

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

How Enzymes work in the home and in industry essay This essay aims to explore the ways on how enzymes are used in home and in industry‚ and it aims to explain the advantages and disadvantages of using enzymes in the home and industry. An enzyme is a protein that is formed by the body that acts as a catalyst to cause a certain desired reaction. Enzymes are very specific. Each enzyme is designed to initiate a specific response with a specific result. Firstly‚ the AQA Science Biology textbook published

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start
