Question 30 (1 point) Which one of the following serum enzymes becomes elevated during the first 24 hours following the onset of acute pancreatitis? a) Alkaline phosphatase b) Creatinine phosphokinase c) Lactic acid dehydrogenase d) Amylase
Answers
Question 29
Enzymes are not Found in most tissues because of its large size, they have a short lag time compared to others. Not all enzymes are excreted in urine,the organs like stomach,intestine ,liver plays a key role .It has a short elimination time of less than a minute.In diagnostic purposes it has to under go a purification process
Ans:a)enzyme requires a purification step prior to analysis
Question 30
Pancreatitis is the inflammation of pancreas causing severe acute pain.It produces a enzyme called amylase ,any disease of pancreas will lead to abnormal increased release of amylase.
Alkaline phosphatase are released in hepatobilary disease and in pancreatic tumour
Increase in creatinine phosphokinase indicates muscle or tissue injury
Lactic acid dehydrogenase increase when there is an injury to heart,brain,liver disease,cancer,anaemia
Ans:d)amylase
