<prompt> The phase I reactions of drug metabolism include the following except:HydrolysisReductionOxidationConjugation  <response>: Biotransformation reactions can be classified into: NonsyntheticPhase 1Functionalization reactions: A functional group - OH, -COOH, -CHO, H2, - SH is generated or exposed- metabolite may be active or inactive. Synthetic Conjugation Phase lI reactions: An endogenous radical is conjugated to the drug- metabolite is mostly inactive; except few drugs, e.g. glucuronide conjugate of morphine and sulfate conjugate of minoxidil are active.Certain drugs already have functional groups and are directly conjugated, while others undergo a phase I reaction first followed by a phase II reaction.
