Final answer:
During carbohydrate digestion, starch and disaccharides are broken down into oligosaccharides and disaccharides. Pancreatic amylase breaks down starch and glycogen into maltose, and enzymes in the small intestine further break down disaccharides into monosaccharides. The monosaccharides are then absorbed and used for energy.
Step-by-step explanation:
In the process of carbohydrate digestion, starch and disaccharides are broken down into oligosaccharides and disaccharides.
In the small intestine, pancreatic amylase breaks down starch and glycogen into maltose, a disaccharide. Maltase, sucrase, and lactase are enzymes present in the brush border of the small intestinal wall that further break down disaccharides into monosaccharides. Maltase breaks down maltose into glucose, sucrase breaks down sucrose into glucose and fructose, and lactase breaks down lactose into glucose and galactose.
These monosaccharides are then absorbed by the body and used in metabolic pathways for energy.
