Michaelis-Menten kinetics are used to describe intracellular reactions. Yet [Eo] [So]. In in vitro batch reactors, the quasi-steady-state hypothesis does not hold for [Es] [So]. Similarly, the rapid equilibrium assumption also will not hold. Rationalize why Michaelis-Menten Kinetics and the quasi-steady-state approximation are still reasonable descriptions of intracellular enzyme reactions.
