<prompt> True about isozymes is:They catalyse the same reactionSame quaternary structureSame distribution in different organsSame enzyme classification with same number and name  <response>: The multiple forms of an enzyme catalysing the same reaction are isoenzymes or isozymes. They however differ in their physical and chemical properties which include the structure, electrophoretic and immunological properties, Km Vmax values, pH optimum, relative susceptibility to inhibitors and degree of denaturation.Reference-Haper 30th edition pg -66 satyanarayana pg 105
