PSTI does not interact directly with chymotrypsinogen or with prophospholipase A2. Which of the following sentences best explains the importance of PSTI to the proper functioning of these enzymes? PSTI interacts with enteropeptidase in the lumen of the small intestine, activating enteropeptidase and allowing enteropeptidase to convert chymotrypsinogen and prophospholipase A2 ir their active forms. PSTI does not interact directly with the inactive forms of these enzymes, but it does interact directly with the active forms (chymotrypsin and phosophlipase A2, respectively) and allow them to function properly. PSTI interacts with trypsinogen in the pancreas and pancreatic duct, preventing trypsinogen from being converted to trypsin which would then convert chymotrypsinogen and prophospholipase A2 into their active forms before they reach the small intestine. OPSTI prevents chymotrypsin and phospholipase A2 from returning to their inactive forms by interacting with trypsinogen in the pancreas and pancreatic duct and with trypsin in the lumen of the small intestine.

All of the following are true with respect to alpha-glucosidase inhibitor, except:A. It inhibits intestinal alpha-glucosidase B. It decreases enzymatic conversion of oligo- to monosaccharidesC. It lowers postprandial glucoseD. It causes gastrointestinal disturbances.E. It may cause development of hypertension.
In the intestine, the triacylglycerols must be converted to fatty acids and glycerol by hydrolytic enzymes before transport into enterocytes. Afterward, fatty acids and glycerol are reconverted into triacylglycerols and then packaged into chylomicrons. Suggest why this energy-requiring process is used instead of a direct transport of triacylglycerols into enterocytes.
Which of the following enzymes is unique to the liver? Beta-hydroxybutyrate dehydrogenase HMG-CoA lyase Thiolase 3-Ketoacyl CoA transferase
A patient suffers pancreatic insufficiency as a result of cystic fibrosis. This insufficiency primarily results in the decreased secretion of protease enzymes from the pancreas. Correlate this disorder to the changes in digestive enzyme function.
A patient presents with a rare disorder called Zollinger-Ellison Syndrome. The patient has developed tumors in the small intestine that release hormones that stimulate the stomach to synthesize and secrete large amounts of HCL. How would this disorder disrupt normal digestive enzyme functions?
