Question

which of the following statements accurately describes the relationship between monomers and polymers in biological molecules?
example of monomer and polymer:
monosaccharide
carbohydrate
a. monosaccharides are complex structures formed by the combination of multiple carbohydrates.
b. carbohydrates are made up of repeating units called monosaccharide, which are linked together through chemical bonds.
c. monomers and polymers are unrelated and serve different functions within biological systems.
d. polymers can only be formed from carbohydrates and cannot include proteins or nucleic acids.

Explanation:

• Option A: Monosaccharides are simple sugars (e.g., glucose), not complex structures formed by combining multiple carbohydrates.
• Option B: Carbohydrates include monosaccharides (monomers) and polysaccharides (polymers). Polysaccharides like starch are made of repeating monosaccharide units linked by chemical bonds.
• Option C: Monomers (e.g., monosaccharides) and polymers (e.g., polysaccharides) are related as polymers are made of monomers. They often have related functions (e.g., energy storage for both simple and complex carbohydrates in different forms).
• Option D: Polymers can be formed from various monomers. Proteins (polymers) are made of amino acid (monomer) units, nucleic acids (polymers) are made of nucleotide (monomer) units, and polysaccharides (polymers) are made of monosaccharide (monomer) units.

Answer:

B. Carbohydrates are made up of repeating units called monosaccharide, which are linked together through chemical bonds.
