Which statement is true regarding both starch and cellulose?

Explanation

The statement that is true regarding both starch and cellulose is that they are both polymers of glucose.Both starch and cellulose are composed of glucose monomers linked together, but the type of linkage and the arrangement of glucose units differ. Starch consists of glucose molecules linked by α-1,4-glycosidic bonds and sometimes α-1,6-glycosidic bonds, making it a storage polysaccharide in plants. Cellulose, on the other hand, consists of glucose molecules linked by β-1,4-glycosidic bonds, forming a structural polysaccharide in plant cell walls.The other statements are not true:C. They cannot both be digested by humans. Humans can digest starch but not cellulose because we lack the necessary enzymes to break the β-1,4-glycosidic bonds in cellulose.B. They are not geometric isomers of each other. Geometric isomers are a type of stereoisomer with a different spatial arrangement of atoms around a double bond. Starch and cellulose are not isomers of each other.D. While starch is used for energy storage in plants, cellulose is primarily used for structural support in plant cell walls, not for energy storage.
