Factors affecting Enzyme- Catalyzed Reactions Prof. Dr. Mohamed Fawzy Ramadan Hassanien Zagazig University, Egypt Factors affecting Enzyme-Catalyzed Reactions 1- Effect of Substrate Concentration (Single-Substrate Reactions) 2- Effect of Inhibitors 3- Effect of pH 4- Effect of Temperature 5- Effect of Pressure 6- Effect of Water -Enzymes in food can be detected only indirectly by measuring their catalytic activity and, in this way, differentiated from other enzymes Extreme pH values could result in the denaturation of enzymes or in order words, the complete loss of function and activity. 2.1. Affecting Enzyme Activity Enzymes. Effect of Temperature • The optimal temperatures of the enzymes in higher organisms rarely exceed 50 °C. • Some enzymes lose their activity when frozen. • Enzymes from thermophilic bacteria found in hot springs are active at 100 °C when enzyme concentration was increased from 1.0% to 1.5% but became constant at concentration exceeding 1.5%. An enzyme concentration at 1.5% was subsequently used in the study of the effect of the other parameters. It was found that the value of the DH also increased when the temperature was increased from 30 to 40°C. However, the hydrolysis a

Factors affecting enzyme activity 1. Temperature Enzymes have an optimum temperature - this is the temperature at which they work most rapidly. Below the optimum temperature, increasing temperature will increase the rate of the reaction SBI4U -VS Name: Natalia Djogo Virtual Lab: Factors Affecting Enzyme Activity Total Marks : / 34 Purpose : - To perform an experiment investigating the factors which affect enzyme functions due to disturbances in structure. Students will create hypotheses and test them using an online virtual lab, using excel to graph their results. The experiment can be done in pairs or individually The net effect of a non competitive inhibitor is to change the shape of the enzyme and thus the active site, so that the substrate can no longer interact with the enzyme to give a reaction. Competitive inhibition is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the sunstrate and vice versa
