Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

ROLE OF BACTERIOPHAGES IN GENETICS AND MOLECULAR BIOLOGY INTRODUCTION AND DISCOVERY: A bacteriophage is any one of a number of viruses that infect bacteria. Bacteriophages are among the most common biological entities on Earth. The term is commonly used in its shortened form‚ phage.Typically; bacteriophages consist of an outer protein capsid‚ enclosing genetic material. The genetic material can be ssRNA‚ dsRNA‚ ssDNA‚ or dsDNA along with either circular or linear arrangement. Bacteriophages are

Using Freezing-Point Depression to Find Molecular Weight Formal Lab Report Purpose: The purpose of this lab is to be able to use the freezing point of a substance to find the molecular weight of it. To do this‚ we will use the Logger Pro program to obtain the freezing point of lauric acid and a solution of benzoic acid and lauric acid. Then‚ we’ll go calculate the freezing point depression of the solution and the molecular weight of benzoic acid. Procedure Summary: Obtain lab goggles

Low Molecular Weight Heparin Paper Low molecular weight heparin is typically used for patients who need to be treated for deep vein thrombosis. Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein usually in the legs. These clots are dangerous because they can break loose‚ travel through the bloodstream to the lungs‚ and block blood flow in the lungs (pulmonary embolism). There are many reasons why clots form in a patient. Mainly
