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. |
Homework Answers
The correct answer is c. pancreatic proteases are endopeptidases.
Pancreatic enzymes like trypsin, chymotrypsin and elastase are endopeptidases that break peptide bonds within protein molecule, except carboxypeptidases that cleaves single amino acid from C- terminal end
Aminopeptidases and dipeptidases are required for complete breakdown of proteins to amino acids

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.

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...
