Question

what is the relationship between starch and glucose?
glucose is a polymer of starch
glucose is unrelated to starch
starch is a polymer of glucose monomers
starch is a monomer of glucose

Explanation:

To determine the relationship between starch and glucose, we recall biochemical concepts: Monomers are single units, and polymers are long chains of monomers. Glucose is a monosaccharide (monomer), and starch is a polysaccharide. Starch is formed by linking many glucose molecules (monomers) together.

• Green option: Incorrect, as polymers are made of monomers; starch would be the polymer, not glucose.
• Blue option: Incorrect, as starch is a carbohydrate made of glucose units.
• Red option: Correct, since starch is a polymer with glucose as its monomer.
• Cyan option: Incorrect, as monomers form polymers (starch is the polymer, glucose the monomer, not vice versa).

Answer:

C. Starch is a polymer of glucose monomers (assuming the red option is labeled as C; if the red option's identifier is, e.g., "Third option (red): Starch is a polymer of glucose monomers", then the answer would reflect that identifier and text.)
