In which part of body maltose convert to Glucose?

The correct answer is Small intestine because it is the primary site where the final stages of carbohydrate digestion occur, specifically the breakdown of disaccharides like maltose into monosaccharides such as glucose. The walls of the small intestine produce enzymes, including maltase, which specifically catalyzes the hydrolysis of maltose into two molecules of glucose. This enzymatic action is crucial for the absorption of glucose into the bloodstream, as only monosaccharides can be directly absorbed.

• Stomach is incorrect because its primary role is protein digestion, and its highly acidic environment inactivates salivary amylase, which starts carbohydrate digestion. There are no enzymes in the stomach to break down maltose.
• Large intestine is incorrect because its main functions are water absorption and the formation of feces. Very little, if any, chemical digestion of carbohydrates takes place here; most digestible nutrients have already been absorbed by the small intestine.
• Liver is incorrect because while the liver plays a vital role in metabolism and processing absorbed nutrients (like converting glucose into glycogen or vice versa), it does not perform the enzymatic breakdown of maltose into glucose directly within the digestive tract. The liver processes substances after they have been absorbed from the small intestine.
