<prompt> True about isoenzymes isareDifferent km valueConsist of multimeric complexHave different physical propertiesAll of these  <response>: Consist of multimeric complex e i.e., Have different physical propertiesisozymes are the physically distinct forms of the same enzymes that catalyze the same reaction, and differ from each other structurally, electrophoretically and immunologically.They differ in their physical properties because of genetically determined difference in amino acid sequence.They are separated by electrophoresis as they have different electrophoretic mobility.They have different Kin value.Isoenzyme of an oligomeric enzyme process differ in combination of its peptide protomer.
