Even though amylose and cellulose contain the same repeating unit of glucose,they are very different in terms of function.Why?
A) A glycosidic bond cannot be cleaved.
B) The orientations of the glycosidic bond are different.
C) ATP cannot be generated from amylose.
D) There is no structural difference between the polymers.

Question

Quizplus · Accepted Answer

The orientations of the glycosidic bond are different. In amylose, the glucose units are connected by alpha-1,4-glycosidic bonds, whereas in cellulose, the glucose units are connected by beta-1,4-glycosidic bonds. This difference in orientation leads to very different structures and functions for the two polysaccharides. Amylose is a linear polymer that is used for energy storage in plants, while cellulose forms rigid, fibrous structures in cell walls and provides structural support.
