what occurs when an inducer is added to a medium containing an organism with a metabolic pathway controlled by a repressor?

Here is the option.

A. The inducer combines with the repressor and causes the repressor to bind to DNA

B. The inducer combines with the repressor and causes the repressor to dissociate DNA

C. The inducer combines with the substrate and blocks induction

D. The inducer combines with the substrate and activates induction

E. The inducer does not combine with repressor but functions as a chaperone molecule for the enzyme-substrate complex

The correct option is C.

The inducer combines with the substrate and blocks induction

Explanation:

Enzymes inducers are drugs or enzymes that Induces or bring out the activity of enzymes been expressed.

This drug increases the metabolic activity of an enzyme either it binded to the enzymes or in a away cause an increase gene code of an enzyme to be expressed.

When an inducer is added to a medium containing an organism with metabolic pathway controller by a repressor it will combine with the repressor and block induction because an enzyme repressor regulate enzyme activity in a negative way by reducing it's synthesis rate.

i think the answer is b.

b is the answer and if you need further with anything message me
