For a simple enzymatic reaction that involves only one substrate and follows Michaelis-Menten kinetics, the changes in the concentrations of substrate, product, free enzyme, and the enzyme-substrate complex over the course of the reaction are depicted by solid curves in the graph below. Which curve (1 to 4) corresponds to [ES]? Write down the number as your answer.

After a brief initial period of pre-steady state, the concentration of the formed ES complexes remains more or less constant in the apparent steady-state phase. This assumption allows the derivation of the Michaelis-Menten equation for reaction rate that involves Vm??, Km, and [S].
