Online Enzyme Lab Simulation

Document Content and Description Below

Online Enzyme Lab Simulation Purpose/Background: In this investigation you will determine the effects of substrate concentration and pH on the initial rate of an enzyme-catalyzed reaction. You will ... be testing two separate questions/hypotheses during this virtual simulation. Each simulated test tube contains the same enzyme solution. You will adjust the pH levels or the amount of substrate added to collect the necessary data. The initial reaction rate is given as the number of product molecules formed during the first minute for each test tube. Lab URL: http://glencoe.mheducation.com/sites/dl/free/0078695104/383930/BL_11.html Question: 1) How does substrate concentration affect enzyme controlled reactions? It will increase the rate of the reaction. 2) How does pH affect enzyme controlled reactions? Has several effects on the structure Hypotheses: 1) the substrate concentration protect inside the enzyme. 2) pH cleans the enzyme and it changes the reactions.. Procedure: ● pH level is adjusted by clicking the up or down arrows below the corresponding test tube ● to add substrate, click and drag the weighing paper to the appropriate test tube ● for all trials, assume the enzyme concentration in each test tube is constant (the same for each) [Show More]
