All of the following are polysaccharides except:
Correct answer: D. Glucose
- A. Glycogen
- B. Cellulose
- C. Starch
- D. Glucose
Explanation
Glucose is the correct answer because it is a monosaccharide, meaning it is a single sugar unit and not a polysaccharide. Polysaccharides are complex carbohydrates composed of many sugar units linked together. Cellulose and starch are both polysaccharides, with cellulose consisting of beta glucose units and starch comprising alpha glucose units. Therefore, glucose is the only option that is not a polysaccharide.
