If the activity of threonine deaminase is completely inhibited, would you expect greater concentrations of threonine to increase activity?

No, greater concentrations of threonine would not be able to out-compete the inhibitor, so inhibition would continue. Competition between the substrate and the regulatory molecule occurs when both molecules are capable of binding to the active site; this is known as competitive inhibition
