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

elements in order by the weight that he saw. As the weights grew from time to time the attributes of one element may be similar to those Mendeleev listed. So Mendeleev would put the elements in a column that were alike chemically (Tro, 2009). All chemicals in the vertical rows of the periodic table were considered to be family because the attributes were a lot alike. In group 1A of the table of elements are the alkali metals, in column 7A are the halogens (Tro, 2009). Noble gases are in the column
