Which of the following is Not in the pancreatic juice?

Explanation

Option D is correct as pancreas is a heterocrine gland which also produces hormone named as insulin and glucagon which are produced by the beta cells and alpha cells respectively. The hormone insulin functions to decrease the glucose level of blood while the hormone glucagon works to increase the glucose level. Thus the hormones work contrary to each other. Read the following paragraph to have a better understanding of pancreas. The enzymatic component of the pancreatic juice is produced by the acini cells of the pancreas and is important for the digestion of all major classes of food. Without the enzymes produced by the pancreas, lipids, proteins, and carbohydrates are not adequately digested. The proteolytic pancreatic enzymes, which digest proteins, are secreted in inactive forms, whereas many of the other enzymes are secreted in active form. The major proteolytic enzymes are trypsin, chymotrypsin, and carboxypeptidase. They are secreted in their inactive forms as trypsinogen, chymotrypsinogen, and procarboxypeptidase and are activated by the removal of certain peptides from the larger precursor proteins. If these were produced in their active forms, they would digest the tissues producing them. Trypsinogen is activated by the proteolytic enzyme enterokinase (meaning, intestinal enzyme), which is an enzyme attached to the brush border (microvilli) of the small intestine. Trypsin then activates more trypsinogen, as well as chymotrypsinogen and procarboxypeptidase. Pancreatic juice also contains pancreatic amylase, which continues the polysaccharide digestion that was initiated in the oral cavity. In addition, pancreatic juice contains a group of lipid digesting enzymes called pancreatic lipases, which break down lipids into free fatty acids, glycerides, cholesterol, and other components. Enzymes that reduce DNA and ribonucleic acid to their component nucleotides, deoxyribonucleases and ribonucleases, respectively are also present in pancreatic juice.
