<prompt> All of the following enzymes are active within a cell except:TrypsinFumeraseHexokinaseAlcohol dehydrogenase  <response>: Ans. is a ie Trypsin Ref: Guyton and Hall, 10e, p746; Harpers Biochem, 26e, p76.Trypsin is a powerful pancreatic proteolytic enzyme which would digest the pancreatic cell that produced it, if not have been produce as a proenzyme - its inactive form known as trypsinogen. Trypsinogen is activated in the intestinal tract by enzyme called enterokinase.Pancreas has additional protective mechanism against self digestion by Trypsin - Secretion of trypsin inhibiter.All other options are enzymes of the glycolytic pathway which are in their active form within the cells.
