If prosecretin, the inactive form of the hormone secretin, is produced improperly and cannot be converted to the active form as a result, how will this affect the intestine and the pancreas during digestion?
A. Cholecystokinin will not be released from the intestinal wall, so the acid of the chyme will not be neutralized. The duodenum will form peptic ulcers due to acid erosion.
B. Acute pancreatitis will occur, as secretin will form within the pancreas and cause pancreatic juices to begin to digest pancreatic tissues.
C. Enzyme-rich pancreatic juice will not be released from the pancreas as chyme is emptied into the duodenum. Proteins, fats, carbohydrates, and nucleic acids will not be digested.
D. Alkaline pancreatic juice will not be released from the pancreas as chyme is emptied into the duodenum. Peptic ulcers may result.
