When the level of glucose in your blood is high, your body is able to store excess glucose in the liver by forming glycogen. When blood glucose levels fall, this stored glucose can be released. Based on this information, which of the following is true?

Question

Quizplus · Accepted Answer

Glycogen is a polysaccharide made up of multiple units of glucose that are polymerized by forming α(1-4) glycosidic bonds. When the body has an excess amount of glucose, the glucose molecules are joined together to form glycogen. When glucose levels drop, the stored glycogen can be broken down into glucose molecules and released into the bloodstream. Therefore, option C, "Glycogen is a polysaccharide formed by joining excess monosaccharides of glucose", is true. The other options are incorrect because glucose is an organic molecule and not a polysaccharide (option B), and glycogen is not a functional group (option D) but rather a complex carbohydrate made up of multiple glucose units. Option A is also incorrect because glucose is a monosaccharide, not a polysaccharide, and cannot "join" to form glycogen.
