The most specific enzyme for acute pancreatitis
- A.
ACP
- B.
AMS
- C.
LPS
- D.
LDH
Correct Answer
C. LPSExplanation
LPS (lipopolysaccharide) is the most specific enzyme for acute pancreatitis. LPS is a component of the outer membrane of certain bacteria, and its presence in the bloodstream is a marker of bacterial infection. In acute pancreatitis, LPS can enter the bloodstream due to inflammation and damage to the pancreas. Therefore, elevated levels of LPS can indicate the presence of acute pancreatitis. ACP (acid phosphatase), AMS (amylase), and LDH (lactate dehydrogenase) are enzymes that can also be elevated in acute pancreatitis, but they are not as specific to this condition as LPS.Rate this question:

- A.
CNP
- B.
CNPG2
- C.
G3
- D.
CNPG3
Correct Answer
A. CNPExplanation
In colorimetric methods for AMS determination, CNP (p-nitrophenyl phosphate) is the end product that is directly measured to estimate enzyme activity. CNP is a substrate that is cleaved by the enzyme being studied, resulting in the release of p-nitrophenol. The amount of p-nitrophenol produced is directly proportional to the enzyme activity, and it can be measured by its absorbance at a specific wavelength. Therefore, CNP is the correct answer as it is the end product that is directly measured in this method.Rate this question:

Converts starch to glucose and maltose
- A.
Malate dehydrogenase
- B.
Amylase
- C.
Creatine kinase
- D.
Lactate dehydrogenase
Correct Answer
B. AmylaseExplanation
Amylase is an enzyme that converts starch into glucose and maltose. This process is known as amylolysis and occurs in the digestive system. Amylase breaks down the long chains of starch molecules into smaller sugar molecules, such as glucose and maltose, which can be easily absorbed by the body. Therefore, amylase plays a crucial role in the digestion and absorption of carbohydrates in the body.Rate this question:

- A.
Saccharogenic
- B.
Amyloclastic
- C.
Chromogenic
- D.
Coupled enzymatic method
Correct Answer
B. AmyloclasticExplanation
The correct answer is "Amyloclastic" because it is a method for AMS determination that follows the 1st order enzymatic reaction. This method involves the enzymatic breakdown of amylose, a component of starch, into smaller fragments. The rate of this enzymatic reaction can be measured to determine the concentration of AMS (amylose) present in a sample. Other options like "Saccharogenic" and "Chromogenic" do not specifically mention the enzymatic breakdown of amylose, while "Coupled enzymatic method" is a more general term that does not specifically indicate the 1st order enzymatic reaction for AMS determination.Rate this question:
