Question

what is the monomer of carbohydrates?
nucleotides
monosaccharide
amino acid
fatty acid
rewatch

Explanation:

To determine the monomer of carbohydrates, we analyze each option:

• Nucleotides are monomers of nucleic acids (like DNA/RNA), not carbohydrates.
• Monosaccharides (e.g., glucose, fructose) are the basic building blocks (monomers) of carbohydrates. Complex carbohydrates (polysaccharides) are formed by linking monosaccharides.
• Amino acids are monomers of proteins.
• Fatty acids, along with glycerol, form lipids (fats), not carbohydrates.

Answer:

B. monosaccharide (assuming the options are labeled A to D with A as nucleotides, B as monosaccharide, C as amino acid, D as fatty acid; if the original labeling is different, adjust the identifier but the correct option text is "monosaccharide")
