Final answer:
The incorrect statement is that carbohydrate absorption occurs in the stomach. Carbohydrate digestion begins in the mouth and continues in the small intestine, where monosaccharides are finally absorbed into the bloodstream.
Step-by-step explanation:
The statement that is incorrect about how carbohydrates are absorbed is: Absorption occurs in the stomach. Carbohydrate digestion begins in the mouth with salivary amylase acting on starches. This process then continues in the small intestine, where pancreatic amylase breaks down the starches further into maltose, and then finally into monosaccharides like glucose, fructose, and galactose. These monosaccharides are then absorbed across the epithelium of the small intestine and enter the bloodstream through various mechanisms such as active transport and facilitated diffusion.
Absorption of carbohydrates is not a significant process that occurs in the stomach. Instead, the stomach's primary role in carbohydrate digestion is to churn food to mix it with gastric juices, thus facilitating its later digestion in the small intestine.
