what type of structure do starch molecules have to allow multiple points of digestion to release glucose molecules?
○ a branching structure
○ a single chain structure
○ a cyclical structure
○ a helical structure

Explanation:

Starch (specifically amylopectin, a component of starch) has a branching structure. The branches provide multiple sites (glycosidic linkages) where enzymes can act to break down the starch into glucose. A single chain would have fewer digestion sites, a cyclical structure is not typical for starch's digestion - enabling form, and a helical structure (like amylose’s helix) is more about storage/structure, not multiple digestion points. So the branching structure allows multiple points of digestion.

Answer:

a. a branching structure
