Question

which of the following is a monomer of carbohydrates? options: nucleotide, fatty acid, amino acid, monosaccharide

Explanation:

To determine the monomer of carbohydrates, we recall the structure of carbohydrates. Carbohydrates are made up of sugar units. Monosaccharides are the simplest form of carbohydrates and act as the monomers (building blocks) for more complex carbohydrates (like disaccharides, polysaccharides). Amino acids are monomers of proteins, fatty acids are part of lipids (along with glycerol), and nucleotides are monomers of nucleic acids (DNA, RNA). So the monomer of carbohydrates is monosaccharide.

Answer:

Monosaccharide (the option with label corresponding to "Monosaccharide" among the given choices, e.g., if it's the first option with the cyan bar, then the answer is the option representing Monosaccharide)
