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.
