The pH of the pancreatic juice is A) 6.4 B) 8.6 C) 12.0 D) 7.0
Hint:Pancreatic juice is an extremely rich source of proteins generated from pancreatic cancer cells , making it suitable to find biomarkers. The pancreatic juice contains alkaline fluid as well as enzymes.
Complete Answer: pH is a quantitative measure of the acidity or basicity of aqueous and other liquid solutions. A solution with a pH lower than 7 is known to be acidic. A solution with a pH greater than 7 is considered to be basic or alkaline. The pH is typically measured with a pH metre, that transforms the difference in electromotive force between the appropriate electrodes placed in the solution to be tested into pH readings. The pancreas is an organ in the abdomen. It plays a vital role in turning the food we consume into a fuel for the cells of the body. The pancreas has two primary functions: an exocrine mechanism that supports digestion and an endocrine function which controls blood sugar. The pancreas contains exocrine glands that generate enzymes that are essential for digestion. When food reaches the intestine, these pancreatic juices are released into the duct system. The pancreas secretes the pancreatic juice. Pancreatic juice includes the following enzymes: trypsinogen, chymotrypsinogen, procarboxypeptidase, amylase , lipase and nuclease. The pH of the pancreatic juice is approximately 8.6, which is alkaline. It's alkaline since it has a high concentration of bicarbonate ions.
Thus the correct answer is option B, 8.6.
Note:Bicarbonate in pancreatic juice is useful for neutralising acidic gastric acid, allowing for successful enzyme modifications. Pancreatic juice secretion is mainly regulated by secretion and cholecystokinin hormones.
