Glycogen, the primary storage polysaccharide in animals, exhibits a highly branched structure. Which of the following best explains the significance of this branching for its function?
Branching increases the structural rigidity of glycogen, enabling it to form strong fibers.
Branching decreases the osmotic pressure exerted by glycogen within cells.
Branching facilitates the transport of glycogen across cell membranes.
Branching allows for rapid hydrolysis by providing multiple sites for enzyme action, crucial for quick energy release.
The cyclic structure of glucose is formed due to the reaction between which functional groups within the molecule?
Carboxyl and amino
Aldehyde and hydroxyl
Phosphate and sulfhydryl

Iodine forms a blue color complex with starch but not with cellulose. This difference is primarily due to:
The presence of branching in cellulose.
The higher molecular weight of cellulose.
Difference in glycosidic linkages and resulting structural conformations.

Chitin, a structural polysaccharide found in the exoskeleton of arthropods, differs significantly from cellulose in terms of its monomeric unit. This difference primarily stems from:
The presence of an N-acetyl group at C-2 of the monomer

The degree of polymerization (chain length)
The three-dimensional arrangement of the polymer chains
