Question

1. Which is not a function of the pancreas?

   		The secretion of Amylase when stimulated by CCK.
   		The secretion of Carboxypeptidase, which breaks down polypeptides to peptides.
   		The secretion of Trypsin, which breaks down polypeptides to peptides.
   		The secretion of Insulin from beta cells to lower blood sugar when stimulated by CCK.
   		The secretion of Glucagon from alpha cells to raise blood sugar by causing glycogen to be broken down to glucose in the liver and muscle.

Answer 1

Answer

Option D) The secretion of Insulin from beta cells to lower blood sugar when stimulated by CCK.

• Insulin is secreted by the endocrine portion of the pancreas known as Islets of Langerhans.
• Beta cells of Islets of Langerhans secrete insulin when blood glucose levels are high.
• Insulin promotes conversion of glucose into glycogen in liver and muscle cells.
• CCK is a hormone secreted by enteroendocrine cells of small intestine that stimulates exocrine part of pancreas to release digestive enzymes (amylase, carboxypeptidase, trypsin, lipase).

Hence, the statement above is not a function of the pancreas.
