Which term is used to describe enzymes that are produced only when specific substrates are present in the environment?

The term that is used to describe enzymes that are produced only when specific substrate are present is Enzyme Specificity.

Explanation:

Enzyme substrate interraction is highly specific in nature.Enzyme contain amino acids in its active site which interract with the substrate.

    Examples

1  Glucokinase enzyme is specific for hexose  sugar glucose .The Glucokinase enzyme will not act on fructose or galactose.

2 Cholesteryl esterase is specific for only cholesterol ester. This enzyme does not act on triaclyglycerol.

3  Carboxypeptidase is specific to cleave the peptide bond present in the carboxy terminal end of the target polypeptide.

i think that the best answer would be c.
