Question

the diagram shows the structure of starch, a complex carbohydrate. what best describes the relationship between starch and glucose?
starch
starch and glucose are reactants that combine to form nucleic acids.
starch is a polymer made of glucose monomers.
starch is a monomer that is used to make glucose.
starch and glucose are reactants that combine to form proteins.

Explanation:

• Option 1: Starch and glucose are carbohydrates, not reactants for nucleic acids (which are made of nucleotides).
• Option 2: Starch is a polysaccharide (polymer). Polymers are made of repeating monomer units. Glucose is a monosaccharide (monomer), and starch is formed by linking glucose units together.
• Option 3: Starch is a polymer, not a monomer. Glucose is the monomer.
• Option 4: Starch and glucose are carbohydrates, not reactants for proteins (which are made of amino acids).

Answer:

Starch is a polymer made of glucose monomers.
