<prompt> True regarding isozymes is:Forms of the same enzymes that catalyze different reactionForms of the same enzymes that catalyze same reactionForms of the different enzymes that catalyze different reactionForms of the different enzymes that catalyze same reaction  <response>: IsozymesIsoenzymes are different forms of same enzyme,catalyzing same reaction in same species, Example:- There are five isozymes of Lactate Dehydrogenase LDH-1 to LDH-5, All conve Pyruvate to Lactate. Same for Isoenzymes Reaction Species Different for Isoenzymes Structure subunits Km, Vmax Electrophoretic mobility Genes but closely relate Heat stability Susceptibility to inhibitor If species different, then it is known as Alloenzyme Isoenzymes may be present in samedifferent tissues
