Question

monomers of carbohydrates
which is the monomer of a polysaccharide?
disaccharide
starch
cellulose
monosaccharide

Explanation:

To determine the monomer of a polysaccharide, we analyze each option:

• Disaccharide: A disaccharide is formed by two monosaccharides linked together, so it is not a monomer.
• Starch: Starch is a polysaccharide (a polymer of monosaccharides), not a monomer.
• Cellulose: Cellulose is also a polysaccharide (a polymer of glucose, a monosaccharide), not a monomer.
• Monosaccharide: Monosaccharides are the simplest form of carbohydrates and are the building blocks (monomers) that combine to form larger carbohydrates like disaccharides (two monosaccharides) and polysaccharides (many monosaccharides).

Answer:

D. Monosaccharide
