B)heat the solution to 90°C.
C)add more substrate.
D)add an allosteric inhibitor.
E)add a noncompetitive inhibitor.

If the substrate is saturated, it means all the enzyme molecules are already bound to substrate molecules. Therefore, the addition of more substrate will not increase the rate of reaction. On the other hand, adding more enzyme molecules will allow more substrate molecules to be bound and converted to products, thus increasing the rate of reaction. Heat, allosteric inhibitors, and noncompetitive inhibitors can all have negative effects on enzyme activity and may decrease the rate of product yield.
