Until the reactants run out
The main thing that an enzyme does to catalyze a reaction, is to lower the energy of reaction.

Enzymes are highly efficient catalysts, and only small quantities are needed to catalyze the reaction of relatively large amounts of materials.
An enzyme binds to a specific substrate (reactant) for the reaction catalyzed.
An enzyme catalyzes the reaction by changing the shapes of the molecules that stress the bonds holding together. Therefore the bond is weaker and will break down faster.
The principle reason a little bit of enzyme can catalyze a reaction involving many molecules is that enzymes are not consumed by the reactions they catalyze. Enzymes are typically multi-use entities and will continue acting until all substrates are reacted.
excess cofactor
When a enzyme is inhibited (many proteins are enzymes), it just means that the enzyme will be reduced in its ability to catalyze a reaction. There are a few types of Inhibition like Competitive Inhibition, Noncompetitive Inhibition, and Irreversible Inhibition.
