A mоlecule PRPP cаn be cоnverted tо X by enzyme A (Km = 80 nM) аnd it cаn be converted to Y by enzyme B (Km = 10 nM).  Excess X is more injurious to the cell than excess Y.  To allow both paths to function while protecting against excess X, the cell controls the level of PRPP.  Assume the starting level of PRPP is 100 nM and the cell drops it to 50 nM.  In terms of Vmax, how much will this change affect the production of X vs. the production of Y?  Show your work.
