Many bacteria possess operons that function to detoxify a particular heavy metal $($suchas Pb$).$ The structural genes of these operons encode proteins with functions that includetransport of heavy metals out of cells, subcellular sequestration of metals, or precipitation ofmetals; all functions that serve to remove dissolved metals from the cell. Typically, the metalitself serves as the allosteric effector compound for these operons $($allosteric effectorcompounds as defined in your text include inducers, co$-$repressors, effectors and inhibitors$).$There is high research interest in using such existing or engineered detoxifying operons inbioremediation.A$.$Would detoxifying operons for which the heavy metal is the allosteric effectorcompound be inducible or repressible? Explain your answer in $1$ sentence.
