Question

Which statement about the pancreatic enzymes is FALSE?

a. Pancreatic enzymes includes disaccharidases that cleave maltose and lactose
b. Pancreatic enzymes can digest triglycerides, carbohydrates and protein
c. The pancreatic enzyme trypsinogen is activated by enzymes on the brush border membrane
d. Pancreatic enzymes are produced by acinar cells
e. Pancreatic enzymes are released as proenzyme precursors

Answer 1

The false statement is that pancreatic enzymes include disaccharidases like maltase and lactase; these enzymes are actually brush border enzymes in the small intestine.

Step-by-step explanation:

The statement about the pancreatic enzymes that is FALSE is: a. Pancreatic enzymes includes disaccharidases that cleave maltose and lactose. Pancreatic enzymes do digest triglycerides, carbohydrates, and proteins, and are indeed produced by acinar cells of the pancreas. This activation occurs in the duodenum, where enteropeptidase converts trypsinogen into trypsin. Trypsin then activates other pancreatic enzymes, such as procarboxypeptidase and chymotrypsinogen.

They are also released as proenzyme precursors. However, disaccharidases such as maltase and lactase are not pancreatic enzymes; they are found in the brush border of the small intestine. The precursor enzyme trypsinogen is activated by brush border enzymes such as enteropeptidase, which converts trypsinogen into trypsin in the small intestine, not in the pancreas itself.
