Homework Answers
Answer: Gastrin – Stimulates the secretion of gastric acid.
Explanation: Gastrin stimulates stomach cells (Parietal cells) to secrete gastric acid (HCL).
Answer: Cholecystokinin – Stimulates the secretion of digestive enzyme from the pancreas and bile from the gallbladder.
Explanation: Cholecystokinin is a hormone secreted by duodenum cells (mucosal epithelial cells). Fats and protein digestion are mediated by this hormone.
Answer: Secretin – Stimulates the secretion of bicarbonate from the pancreas.
Explanation: Secretin is a hormone which functions in response to acidic environment. The hormone then stimulates the pancreatic cells (acinar cells) to secrete bicarbonate so that the acidity environment in the duodenum could be controlled.
Answer: Chyme – Stimulates the duodenum to secrete Cholecystokinin and secretin.
Explanation: The partially digested food which moves from stomach to small intestine is known as chyme. Chyme is acidic hence it will stimulate the secretin production to control acidity. Chyme is partially digested food, hence it stimulates Cholecystokinin to digest fat and protein.
Answer: Secretin and Cholecystokinin – Inhibits the secretion of gastric juice.
Explanation: Gastrin in inhibited by this hormone which in turn results inhibition of HCL production by parietal cells of stomach.

Which statement about protease secretion and activity during protein digestion is correct? A. Pepsin is a protease that degrades proteins in the small intestine. B. Secretin is a protease that neutralizes stomach acid during digestion. C. Cholecystokinin (CCK) triggers active protease secretion from the pancreas. D. Trypsinogen is a protease that converts zymogens into active proteases. E. Trypsinogen is the substrate of enteropeptidase in the small intestine.

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...
