Which polysaccharide is not broken down by α-amylase?

Question

Quizplus · Accepted Answer

α-amylase is an enzyme that breaks down starches into smaller sugars, but it cannot break down cellulose as it has a different glycosidic bond that is not recognized by this enzyme. Glycogen and amylopectin are both starches that are broken down by α-amylase. "Amylase" is also not a polysaccharide but rather an enzyme that breaks down polysaccharides, so it is not a valid answer choice.
