What is the difference between the glycosidic bond (dehydrated joining of two glucose monomers) in cellulose vs amylose or glycogen?

a) In cellulose the linkage has the oxygen of the precursor sugar above the plane of the ring

b)in amylose and glycogen the linkage has the oxygen of the precursor monosaccharide below the plane of the ring

c)there is no difference in these glycosidic bonds

d)A and B are both true

What is the difference between starch and cellulose? What is the difference between starch and cellulose?

A) In cellulose, the polymer is assembled using fructose instead of glucose. Cellulose is similar to glycogen in that it is used for short-term energy storage because the bonds can be easily hydrolyzed. Starch is used for long-term energy storage.

B) Cellulose can be hydrolyzed into monomers by the human digestive tract, whereas starch cannot.

C) Cellulose is composed of alternating monomers of glucose and galactose, whereas starch is composed of glucose only.

D) The monosaccharide monomers of cellulose differ from those in starch. The human digestive tract cannot hydrolyze these monomers.

E) In cellulose, the glucose monomers are assembled in an alternating pattern on different sides of the linked monomers, and the human digestive tract cannot break the bonds. In starch, the glucose monomers are not alternated and our digestive tract can break these bonds.
