The right answer is D) Hydrolysis of polysaccharides
Polysaccharides can be broken down by hydrolysis of the glycosidic linkages between residues into smaller polysaccharides as well as into disaccharides or monosaccharides. Their digestion inside the cells or in the digestive cavities consists of a hydrolysis catalyzed by digestive enzymes (hydrolases) generically called glucosidases, specific for certain polysaccharides and especially certain types of glucosidic bonds.
Thus, for example, the starch hydrolyzing enzymes whose bonds are of the α type can not decompose the cellulose whose bonds are of β type, although in both cases the monosaccharide is the same. Glucosidases that digest polysaccharides, which may be called polysaccharases, usually break one of the two bonds, releasing disaccharides and allowing other enzymes to complete the work.
