The chemical digestion of the disaccharides occurs in the:

Select one:
a. esophagus
b. stomach
c. large intestine
d. small intestine
e. mouth

Answer :

The chemical digestion of disaccharides takes place in the d. small intestine, where enzymes like sucrase, lactase, and maltase break them down into monosaccharides.

The chemical digestion of disaccharides predominantly occurs in the small intestine. Enzymes such as sucrase, lactase, and maltase are responsible for breaking down disaccharides like sucrose, lactose, and maltose into monosaccharides, which are then ready for absorption into the bloodstream. For instance, maltase cleaves maltose into two glucose molecules. Despite some digestive processes beginning earlier, such as starch digestion by amylase in the mouth, the final and most intensive digestion of carbohydrates occurs in the small intestine.
