LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

Suzuki‚ Laurent Santos‚ Val Justin D.M. Tongco* College of Science‚ University of Santo Tomas‚ Manila Philippines Abstract Salivary amylase‚ found in humans‚ is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors‚ such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. However‚ due to some errors

Enzymatic activity of Human saliva (Salivary amylase) against Temperature Proponent: Ian Angelo P. Dela Cruz BS-Biology 1-3 Prof. McJervis S. Villaruel Professor – BIOL2015(Lab) ABSTRACT This report entitled “Enzymatic activity of Human saliva (Salivary amylase) against temperature” aims to know and observe the enzyme activity of the human saliva. The research only included the use of starch-agar as the medium to observe enzyme activity during the experiment. Five starch-agar

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

Introduction: The purpose of this lab was to check the time needed for salivary amylase and phosphorylase to produce a negative result and how different concentrations affected those times. Enzymes are biological catalysts that can cause a specific chemical change in any part of the body (Walsh‚ 2002). Many of the reactions that take place within a cell would normally take place at temperatures substantially higher than those present inside a cell (Alberts et al.‚ 2010). Because of this‚ these chemical

Enzymatic Activity of Salivary Amylase Abstract: Salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules. In this experiment‚ the enzymatic activity and specificity of salivary amylase was examined depending on the changes in pH and temperature. In the first part of the experiment‚ the effect of temperature was determined‚ using constant temperature bath (4‚ room temp‚ 37‚ 50‚ 60‚ and 70°C). Having the room temp and 50°C as the highest and 37°C as infinite

The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase‚ the key enzyme for starch digestion‚ salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose‚ amylopectin‚ and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency.
