Operons and Feedback Inhibition
Operons are a set of genes that are regulated together as a single unit. They are found in prokaryotes and some lower eukaryotes and consist of an operator, promoter, and structural genes. The operator acts as a switch that can control the expression of the structural genes.
Feedback inhibition is a mechanism where the end product of a metabolic pathway inhibits an earlier enzyme in the pathway. This helps to regulate the amount of product that is synthesized. In operons, feedback inhibition of the biosynthesis of multiple enzymes by a single small molecule is made possible.
True Statement
The true statement about operons is that feedback inhibition of the biosynthesis of multiple enzymes by a single small molecule is made possible by operons. This is because the operon system allows the genes involved in a particular metabolic pathway to be regulated together. The operator can respond to the presence of an inhibitor and prevent the expression of the structural genes, thus reducing the production of the end product.
Other Statements
Option A is incorrect because operons do not regulate individual genes, but rather a set of genes that work together in a metabolic pathway.
Option B is incorrect because operons can regulate genes involved in any metabolic pathway, not just carbohydrate metabolism.
Option D is incorrect because in the case of inducible operons, the inducer binds to the repressor protein, not the operator.
