Inducible enzymes are ones which are either not active or not produced unless their substrate is present or product is needed. This means that the enzyme may need a co-factor to activate it or de-repress it. This may occur at the level of the enzyme or at the level of gene expression.
Take for example the Lac operon. The unit contains a repressor protein, a promoter, an operator and three genes (lac Z, Y and A) ...
