Write an explanation of how any two factors affect the rate of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

Laboratory 2: Scientific Methodology & Enzyme Activity Objective: The purpose of this experiment was to simply measure oxygen production rates released from decomposed hydrogen peroxide under different conditions (concentration of enzymes‚ temperature‚ and PH level). Hypothesis: Part a: If different amounts of enzyme solution are added to the hydrogen peroxide‚ then the highest amount of enzymes will have the greatest reaction rate because enzymes catalyze reactions‚ meaning more oxygen

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Uncontrollable environment affecting organizations‚ affecting international logistic activities Uncontrollable environment is one major condition which is unpredictable and uncertain. Regardless of what it might be‚ an uncontrollable environment will negatively affect any organization effort‚ no matter which function it is and perhaps the objectivities and strategies of the business. Today‚ business is a global market. In one way or another‚ we are all closely connected. The logistics systems have

Microenvironmental factors are “The factors close to the company that affect its ability to serve its customers” [principles of marketing]. The microenvironmental factors that affected the introduction and sale of the Toyota Prius were it customers‚ competitors and publics. Customers are anyone who buys or rents from the company. Customer are the most important microenvironmental factor that affect company as they survive on meeting the wants and needs of the customer and failure to do so will result
