The reaction converted hydrogen peroxide to water and oxygen and oxygen production was used as a measure of enzyme activity. Factors affecting enzyme activity Namrata Chhabra 30-Mar-18 Namrata Chhabra 1 2. Factors Affecting Enzymatic Activity – PPT (Temperature, Water, pH, [Substrate], [Enzyme]) Lecture Note on Factors Affecting Enzymatic Activity. Ø A small amount of enzyme is enough for a large amount of substrate. 3 INTRODUCTION TO ENZYMES Worthington Biochemical Corporation 800.445.9603 Enzymes and Life Processes The living cell is the site of tremendous biochemical activity called metabolism. (5). Factors affecting enzyme activity 1. The enzyme we studied was hydrogen peroxidase from a cow. 1 What are the factors affecting Enzyme Activity? PPT – Lecture 3: Factors affecting enzyme activity: [substrate] and inhibitors PowerPoint presentation | free to view - id: 1abb51-ZDc1Z. 1. 20.3 Factors Affecting Enzyme Activity The activity of an enzyme describes how fast an enzyme catalyzes the reaction and is strongly affected by reaction conditions, such as temperature. Ø Enzymes have extraordinary catalytic power. ... Factors Affecting Enzyme Activity. Make a dilution of the enzyme so that you have 3 strengths of enzyme: one at 200% enzyme strength (~4 mL solution), one at 100% enzyme strength (~4 mL), and one at 2 Recap 3 What are enzymes? • Enzymes are biological catalysts of the chemical reactions. Factors affecting EnzymeCatalyzed Reactions 2. Factors affecting enzyme function Temperature Optimum T° greatest number of molecular collisions human enzymes = 35°- 40°C body temp = 37°C Heat: increase beyond optimum T° increased energy level of molecules disrupts bonds in enzyme & between enzyme & substrate H, ionic = weak bonds
