Which macromolecule includes simple sugars and starches?

• A. Lipids
• B. Nucleic Acids
• C. Carbohydrates
• D. Proteins

Answer: (C)

Carbohydrates are the macromolecules that include simple sugars and starches. Simple sugars, like glucose, are the building blocks of carbohydrates (monosaccharides), while starch is a polysaccharide composed of many glucose units used by plants to store energy. Carbohydrates provide quick, accessible energy because their bonds are relatively easy to break. Other macromolecules serve different roles: lipids are mainly for long-term energy storage and membranes, nucleic acids store genetic information, and proteins perform a wide range of functions from enzymes to structural components. So, the group that covers both simple sugars and starches is carbohydrates.
