Starch and cellulose differ in their properties because
A.their glucose monomers link with different bond orientations
B.starch contains fructose instead of glucose
C.cellulose is a protein
D.starch is made by animals
Explanation
Core Concept
Starch uses α-linkages (digestible, helical); cellulose uses β-linkages (straight chains that hydrogen-bond into tough fibers). The same monomer, different geometry, different function.
Correct Answer
Atheir glucose monomers link with different bond orientations
