<prompt> Ail of the following are Phase II reactions exceptAcetylationMethylationCyclizationGlycine conjugation  <response>: Ans. is c i.e., Cyclization Biotransformation reactions metabolism of drugs can be classified:A. Non-synthetic phase I reactions Metabolism brings about a change in the drug molecule by :1. Oxidation3. Hydrolysis5. Decyclization2. Reduction4. Cyclization B. Synthetic phase II or conjugation reaction Metabolism involves union of the drug with one of several polar water-soluble endogenous molecules that are products of intermediary metabolism, to form a water-soluble conjugate which is readily eliminated by kidney or, if the molecular weight exceeds 300, in the bile. Reactions are:-1. Acetylation4. Glutathione conjugation7. Neucleotide synthesis2. Glucuronide conjugation5. Sulfate conjugation 3. Glycine conjugation6. Methylation
