Question

onstitutive enzyme , repressible enzyme, and inducible enzyme as fast as possible

Answer 1

Dear student,
Constitutive enzyme- These enzymes are produced in constant amounts without regard to the physiological demand or the concentration of the substrate. They are continuously synthesized because they have important role in maintaining cell processes and structure.
Inducible enzyme- is an enzyme that is normally present in minute quantities within cell, but whose concentration increases dramatically when substrate compound is added.
​​​​​​
Repressible enzymes- are usually the enzymes which are involved in biosynthetic or anabolic pathways, e.g. tryptophan synthetase produced by the E. coli when tryptophan (an important amino acid required for synthesizing proteins) is not available from the culture medium.
