Question

select all polysaccharides:
glycogen
cellulose
glucose
starch
amino acid

Explanation:

To solve this, we recall the definition of polysaccharides (complex carbohydrates made of many monosaccharide units).

• Glycogen: A polysaccharide, storage form of glucose in animals.
• Cellulose: A polysaccharide, structural component in plant cell walls.
• Glucose: A monosaccharide (simple sugar), not a polysaccharide.
• Starch: A polysaccharide, storage form of glucose in plants.
• Amino acid: Building block of proteins, not a carbohydrate (let alone a polysaccharide).

Answer:

A. Glycogen, B. Cellulose, D. Starch
