What is the product of disaccharides during carbohydrate digestion?

During carbohydrate digestion, disaccharides are broken down into their monosaccharide components. Disaccharides like sucrose and lactose are composed of two monosaccharides. For instance, sucrose is made up of glucose and fructose, while lactose is made up of glucose and galactose. The digestion process involves specific enzymes, such as sucrase that hydrolyzes sucrose into glucose and fructose, and lactase that hydrolyzes lactose into glucose and galactose. Therefore, the result of digesting disaccharides is the formation of these monosaccharides, primarily glucose, and not another disaccharide like trehalose or the original disaccharides themselves.

The correct understanding is that during carbohydrate digestion, the end products are the monosaccharides rather than any of the disaccharides listed in the choices. Hence, the choice indicating that disaccharides are the final product in carbohydrate digestion is not accurate, leading to the conclusion that the appropriate response is "none of the above."
