Question

Question 29 (1 point) Select which of the following enzyme characteristics would be most useful in diagnostic decision making. a) Enzyme requires a purification step prior to analysis Enzyme is distributed in most tissues, high specificity, low sensitivity and demonstrates b) a short lag time and long elimination time. Enzyme has high sensitivity, high specificity, and demonstrates a short lag time and long c) elimination time. d) Enzyme is cleared in the urine. 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

Answer 1

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
