Glycogen is a polysaccharide of glucose that humans and other animals produce when glucose is in abundance for the purposes of glucose storage. Glycogen is typically stored in muscles and the liver.
Because humans must be able to access the glucose within glycogen during times of glucose need, we produce an enzyme, called glycogen phosphorylase, capable of releasing individual glucose units from glycogen. Plants also produce multiple polysaccharides.
Based upon structural properties, which of the following is a plant polysaccharide on which you might expect glycogen phosphorylase to also be effective at releasing individual glucose units?
