Question

question 21 of 30 which type of monomer combines and forms polysaccharides? a. amino acid b. sugar c. nucleic acid d. phospholipid

Explanation:

To determine the monomer that forms polysaccharides, we analyze each option:

• Option A: Amino acids are monomers of proteins, not polysaccharides.
• Option B: Polysaccharides are complex carbohydrates, and their monomers are simple sugars (monosaccharides). So sugar (monosaccharide) combines to form polysaccharides.
• Option C: Nucleic acids are polymers of nucleotides, not related to polysaccharides.
• Option D: Phospholipids are components of cell membranes, not monomers of polysaccharides.

Answer:

B. Sugar
