Question

Which among the following are compounds structurally similar to substrate and inducing enzyme synthesis?

• A. Constitutive enzymes
• B. Gratuitous inducer
• C. Coordinated inducers
• D. None of the above

Answer 1

The correct option is B Gratuitous inducer

An inducer is a substance that induces, i.e., initiates or increases the synthesis of enzyme molecules. Gratuitous inducer is an analogue of a natural inducer that is capable of inducing an operon while not serving as a substrate for the enzyme being induced.

So, the correct answer is option B.
