An organism has a metabolic pathway that is controlled by an inducer through negative regulation. When this organism is grown in
beks73 [17]

Answer:

The inducer will combines with the repressor and inactivates the pathway.

Explanation:

Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.

In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.

Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
