Starch differs from cellulose specifically in that (select all that apply):

1. Starch is a branched polymer. Cellulose is not branched.

2. Starch is for energy storage, while cellulose is primarily structural.

3. Starch contains alpha-glycosidic linkages between monomers, while cellulose contains beta-glycosidic linkages.

4. Starch is made by animal cells. Cellulose is made by plants.

Colten · Answer 1

option 1, 2, 3

Explanation:

Starch is present in plants and used for energy storage. It is a branched polypeptide and made of two units amylose and amylopectin.

Amylose is linear while amylopectin is branched. Monomer of starch is glucose and two glucose units are joined by aplha-1,4-glycosidic linkages.

Cellulose is a structural polypeptide and present in the cell wall of the plant. It is a linear polymer made of glucose. The two glucose units are joined by the β-glycosidic linkages.

Therefore, among the given, options 1, 2 and 3 are correct.
