-
Bacteria respond to a xenobiotic by recruiting exogenous genes to establish a pathway to degrade the xenobiotic, which is necessary for their adaptation and survival.

Since the liver is the primary site for biotransformation, it is also potentially quite vulnerable to the toxic action of a xenobiotic that is activated to a more toxic compound.

-
A threshold for toxic effects occurs at the point where the body's ability to detoxify a xenobiotic or repair toxic injury has been exceeded.
-
The plasma level of a xenobiotic is important since it generally reflects the concentration of the toxicant at the site of action.
-
Thus, reduction reactions frequently result in activation of a xenobiotic rather than detoxification.
