You have successfully developed two new inhibitors (Alice-1 & Alice-2) for the mutant peptidase mentioned in question To understand how the inhibitors work, you carried out enzyme assays measuring the ability of the mutant peptidase to cleave the substrate in the absence and presence of the two inhibitors and obtained following data:

Using the entire data set to make a diagnostic plot, answer the following:

 

V0, ?M/sec

[S], ?M
