A cotton fiber is mostly cellulose. After treatment with amylase, the fiber remains intact, but a starch solution loses viscosity. Which explanation best connects these observations to carbohydrate arrangement?
A
Amylase strengthens cotton because it adds alpha-1,6 branches to cellulose.
B
Starch loses viscosity because amylase hydrolyzes peptide bonds in proteins mixed with starch.
C
Amylase hydrolyzes alpha-linked starch chains but not the beta-linked cellulose chains that form cotton fibers.
D
Cotton remains intact because cellulose contains no glucose and therefore no glycosidic bonds.
