In prokaryotes, gene expression is often responsive to small molecules where increasing synthesis of enzymes for metabolism of a certain substrate is termed ____ and the substrate is called ____. Likewise metabolic products that decrease synthesis of enzymes for their production are called ____ and carry out ____.
A) autoregulation; regulatory; co-repressors; initiation
B) co-induction; induction; co-repressors; initiation
C) induction; co-inducer; co-repressors; repression
D) induction; co-inducer; repressor; co-repression
E) all are true

Question

Induction is the process where the synthesis of an enzyme increases in response to a substrate, which is termed a co-inducer in this context. Co-repressors are metabolic products that decrease the synthesis of enzymes involved in their own production, a process known as repression.
