Which outcome occurs when continuously increasing an inhibitor concentration in a non-competitive enzymatic reaction?

A)Reaction rate progressively approaches zero
B)Affinity of enzyme increases greatly
C)Substrate saturation occurs prematurely
D)Initial velocity plateaus and stabilizes

💡 Explanation

Increasing inhibitor concentration progressively disables enzymes. The reaction rate asymptotically approaches zero because non-competitive inhibitors reduce enzyme activity via allosteric modulation, rather than directly blocking the active site; therefore, the reaction halts rather than achieving a different equilibrium.
