Briefly discuss the different digestive enzymes present in the intestine for the digestion of disaccharides
Answers may vary. The digestion of disaccharides (maltose, sucrose, and lactose) takes place entirely in the small intestine. The small intestine is the lone source of enzymes needed for disaccharide digestion. Each disaccharide has its own specific digestive enzyme:
Maltase digests maltose, releasing two glucose molecules.
Sucrase digests sucrose, releasing glucose and fructose molecules.
Lactase digests lactose, releasing glucose and galactose molecules.
Once disaccharides have been digested into their component monosaccharides, they can be absorbed across the cells (enterocytes) of the small intestine and circulated in the blood.
