With reference to human beings, consider the following enzymes : I. Carboxypeptidase II. Lipase III. Maltase IV. Surcrase Which is these are found in pancreatic juice?
Explanation
Pancreatic juice is a secretion from the exocrine pancreas containing enzymes essential for digesting proteins, fats, and carbohydrates. According to the provided evidence, pancreatic enzymes include Carboxypeptidase (which cleaves amino acids at the carboxyl end of peptides) and Pancreatic Lipase (which breaks down emulsified triglycerides) [t1, t6]. While the pancreas also secretes amylase to digest starches into disaccharides like maltose, the specific enzymes Maltase and Sucrase are classified as 'brush border enzymes' [t1, t5]. These disaccharidases are located on the luminal membranes of the enterocytes in the small intestine, where they perform the final step of carbohydrate digestion by converting disaccharides into monosaccharides like glucose and fructose [t3, t5]. Therefore, only Carboxypeptidase (I) and Lipase (II) are components of pancreatic juice, whereas Maltase (III) and Sucrase (IV) are found in the intestinal juice (succus entericus).
