Question

which of the following is a biological advantage of storing glucose molecules in branched polymers? they can be stacked together to save space. they have more sites for enzymatic attack than do unbranched polymers. they are insoluble and so provide strength to the molecule. they are resistant to enzymes.

Explanation:

Branched polymers of glucose, like glycogen in animals and amylopectin in plants, have more non - reducing ends. These non - reducing ends are the sites for enzymatic action. Enzymes can break down the polymer to release glucose monomers more quickly in branched polymers compared to unbranched ones due to the greater number of accessible sites. Stacking to save space is not the main advantage. Solubility and providing strength are not the key biological advantages related to branched structure in this context. Resistance to enzymes is the opposite of what occurs as branched polymers are more easily broken down by enzymes.

Answer:

They have more sites for enzymatic attack than do unbranched polymers.
