Enzymes: Virtual Lab Introduction: This is a virtual lab simulation of enzymes and substrates. It teaches about enzymatic activity and how it is affected by substrate concentration and pH. Students are to visualize the virtual lab as an actual lab and conduct the experiment as such. Purpose This investigation will determine the effects of substrate concentration and pH on the initial rate of an enzyme-catalyzed reaction. Materials Computer Pencil/pen Enzymes at various pH Substrates

down even lower? Sue should focus on the startup costs associated with the chemicals. Based upon her discussions with other companies, sue should see a reduction of at least between $750k-$850 dollars in the overall costs that is paid to Chicago Chemical. Chicago Chemical has already been producing the chemical for the past 5 years; therefore, there isn’t any startup costs associated with their production of the chemical. Because of this Sue should be able to reopen negotiations with them. The
