Question

In an environment where an operon codes for enzymes that synthesize a protein from precursor amino acid molecules, what type of enzymes are synthesized?
a) inducible enzymes
b) constitutive enzymes
c) repressible enzymes
d) catabolic enzymes

Answer 1

The correct answer for this question would be repressible enzymes. Repressible enzymes are those which bind to the operator, and then block the attachment of RNA polymerase, which therefore prevents the transciption of genes. From this, we know that these are the types of enzymes that are synthesized in an environment where an operon is needed to code for enzymes that synthesize a protein from precursor amino acid molecules.

Answer 2

I think the right answer is c) repressible enzymes. If you have some questions or want to learn more about enzymes, the link below may be helpful I think: https://www.creative-enzymes.com/cate/Enzymes-For-Industrial-Use_3.html
