Two curves showing the rate versus substrate concentration are shown below for an enzyme-catalyzed reaction. One curve is for the reaction in the presence of substance X. The other curve is for data in the absence of substance X. Examine the curves and tell which statement below is TRUE for the observation made.

In a certain enzyme-catalyzed reaction the following steps occur:1. A phosphate group on substrate A is transferred to a side chain of an active site residue of the enzyme.2. The dephosphorylated form of substrate A dissociates from the enzyme.3. Substrate B enters the active site and is phosphorylated with simultaneous regeneration of the enzyme in its original form.What kind of kinetic mechanism is described?
