* Equilibrium: Equilibrium means the forward and reverse reaction rates are equal. This means the concentrations of substrates and products are not changing.
* Enzymes as Catalysts: Enzymes speed up reactions by lowering the activation energy. They don't change the equilibrium point of a reaction.
* No Net Change: Since the enzyme can't shift the equilibrium, the forward and reverse reactions will continue to proceed at equal rates. There will be no net change in the concentrations of substrates or products.
In essence, the enzyme will be present but inactive because the system is already at its equilibrium point. It won't drive the reaction in either direction.
However, a few things to consider:
* If the enzyme is added to a non-equilibrium system: Then the enzyme will act as a catalyst and accelerate the reaction towards equilibrium.
* If the conditions change: For example, if the temperature or pH of the solution changes, the equilibrium point might shift. The enzyme might then have an effect by helping the system reach the new equilibrium.
