Answer:
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.
