Guida verificata passo dopo passo1
Understand the role of pancreatic enzymes in digestion: the pancreas secretes several enzymes that target different macromolecules such as proteins, lipids, and carbohydrates.
Identify the substrate each enzyme acts upon: pepsin is a protease active in the stomach, lipase breaks down lipids, trypsin is a protease that digests proteins, and amylase hydrolyzes starch, a carbohydrate.
Recall that starch is a polysaccharide composed of glucose units, and its digestion requires an enzyme that breaks down these glycosidic bonds into smaller sugars.
Recognize that pancreatic amylase specifically catalyzes the hydrolysis of starch into maltose and other smaller oligosaccharides in the small intestine.
Conclude that the pancreatic enzyme responsible for hydrolyzing dietary starch into smaller carbohydrates is pancreatic amylase.
