Which outcome arises when a catalyst reaches saturation in enzyme kinetics?

A)Reaction rate reaches maximal velocity
B)Substrate concentration exponentially increases
C)Equilibrium constant becomes temperature-dependent
D)Activation energy linearly increases

💡 Explanation

When the saturation occurs, the rate achieves its maximum because enzyme's active sites are fully occupied and turnover is limited through the Michaelis-Menten kinetics; therefore further increases in substrate concentration won't raise speed, rather than indefinite acceleration.
