[{'content': 'True about isoenzymes is/are \nSelect and explain. \nA. Different km value, B. Consist of multimeric complex, C. Have different physical properties, D. All of these', 'role': 'user'}, {'content': "Answer: D \nExplanation: Consist of multimeric complex & `e' i.e., Have different physical properties\n\nisozymes are the physically distinct forms of the same enzymes that catalyze the same reaction, and differ from each other structurally, electrophoretically and immunologically.\nThey differ in their physical properties because of genetically determined difference in amino acid sequence.\nThey are separated by electrophoresis as they have different electrophoretic mobility.\nThey have different Kin value.\nIsoenzyme of an oligomeric enzyme process differ in combination of its peptide protomer.", 'role': 'assistant'}]
