G The first common step, A⟶BA⟶B , is partly inhibited by both final products, YY and Z, Z, which act independently of each other. Suppose that a high level of YY alone decreased the rate of the A⟶BA⟶B step from 100 s−1100 s−1 to 60 s−160 s−1 and that a high level of ZZ alone decreased the rate from 100 s−1100 s−1 to 40 s−1.40 s−1. What would be the rate of the A⟶BA⟶B step in the presence of high levels of both YY and Z?Z? rate:
