<prompt> The activity of which of the following enzymes is increased in Diabetes Mellitus?CPT-1Phosphoenol Pyruvate carboxykinase PEPCKGlucose-6-PhosphataseAll  <response>: Diabetic situation is same like fasting or starvation i.e. catabolic situation in the body. So, in Diabetes Mellitus, the activity of Catabolic enzymes is increased. Carnitine Palmitoyl Transferase-I CPT-I is an enzyme of b-Oxidation which is a Catabolic pathway. Therefore, it is increased in Diabetes. Option b c - Phosphoenol Pyruvate Carboxykinase PEPCK and Glucose -6-Phosphatase are enzymes of Gluconeogenesis which is a Catabolic pathway and hence increased in Diabetes. So, answer is all.
