1. I have no idea which compound is added to graph 3. The red
line has higher Vmax and same Km, so I thought it was
noncompetitive activator. But it's not.
2. What's the difference between allosteric inhibitor and
noncompetitive inhibitor? I thought both are same because they bind
to the allosteric site rather than the active site. Why does graph
1 represent allosteric inhibitor, and why does graph 2 represent
noncompetitive inhibitor?
Case 1: issr Blue line - Enzyme alone Red line-Enzyme + unknown compound 13 reaction rate substrate concentration The 4 graphs above represent the change in enzyme kinetics with the individual addition of different compounds that could be categorized as either: allosteric inhibitors, allosteric activators, competitive inhibitors, activators or non-competitive inhibitors. UNE Online _Case connections Review the graphs above. Each graph represents the activity of an enzyme and the enzyme + the addition of an unknown compound. By comparing the kinetics of the enzyme alone to the enzyme + unknown, determine what type of compound was added to each of the 4 different solutions to elicit the observed change.
