Question

Alkaline medium is essential for the functioning of pancreatic juice, which is provided by
(A)The secretion of bicarbonate from the liver
(B)The secretion of bicarbonate from the duodenal wall
(C)The secretion of bicarbonate from the pancreas
(D)The secretion of bile salts from the liver

Answer 1

Hint: Bicarbonate ions are helpful in neutralizing the acidic environment of the stomach and also maintain the alkaline nature of pancreatic juice.

Complete answer:
The pancreas is a three-sided organ that stretches out over our mid-region and sits to some degree behind the stomach. The pancreas is a crucial digestive organ since it secretes pancreatic juice into the duodenum. Pancreatic juice is a fluid containing an assortment of catalysts, including trypsin, chymotrypsin, elastase, carboxypeptidase, pancreatic lipase, nucleases and amylase. These compounds are basic for assimilation of the vast majority of the protein, fat, and sugar in the diet. This pancreatic juice is alkaline in nature because of the high grouping of bicarbonate ions. Bicarbonate particles are valuable in neutralizing the acidic gastric environment, taking into account compelling enzymes changes. Subsequently, the basic (alkaline) medium is fundamental for the working of pancreatic juice, which is given by the discharge of bicarbonate from the pancreas.Discharge of pancreatic juice is triggered by hormones of the duodenum, such as secretin and cholecystokinin, and by nervous impulses through the vagus nerve.

Hence the correct answer is option(C)

Note: A normal functioning pancreas secretes about 8 cups of pancreatic juice into the duodenum daily.
