Homework Answers
1) An increase in fatty acids and amino acids within the small intestine stimulates the increase in secretion of CCK.
2) CCK stimulates the release of enzymes from exocrine cells within the pancreas into pancreatic duct.
3)CCK also stimulates the contraction of gall bladder which increases the flow of bile into the common bile duct.
4)The pancreatic duct and commmon bile duct merge at sphincter of oddi , which is opening that leads into small intestine.
5) The third effect of CCK is to mediate the relaxation of sphincter of oddi causing it to open which increases the flow of both bile and pancreatic enzymes in small intestine.
6)the final result is an increase in digestion of fats and proteins within the small intestine.

Pancreatic enzymes cannot catalyze the complete digestion of dietary proteins to amino acids in the intestine because Question 20 options: A. pancreatic proteases are zymogens. B. the pH in the small intestine is unfavorable for activity of pancreatic proteases. C. pancreatic proteases are endopeptidases. D. bacteria destroy pancreatic proteases in the small intestine. E. pepsin from the stomach is required to activate pancreatic proteases.

Each day, the pancreas produces up to 1.5 L of pancreatic juices that enter the duodenum via the pancreatic duct. The pancreatic juices consist of water, salts, bicarbonate ions, and digestive enzymes. Bicarbonate ion raises the pH of the acidic chyme from the stomach, stopping the active ity of pepsin and allowing the pancreatic and intestinal enzymes to function. The various pancre. atic enzymes and their substrates are listed in Table 10.2. Table 10.2 Various enzymes produced by the pancreas...
