Question

3. Which of the following best compares the structures of lipids and carbohydrates?A. Both are made up of monosaccharide monomers, but lipids are hydrophobic and carbohydrates arehydrophilic.B. Both consist of carbon, hydrogen, and oxygen, but their monomers differ; carbohydrates are madeof monosaccharides and lipids are made of fatty acids and glycerol.C. Both contain carbon and hydrogen, but carbohydrates also contain oxygen and lipids containnitrogen.D. Both have a carbon backbone, but lipids have a "ring" shaped molecular structure andcarbohydrates form long chains.

Answer 1

The best comparison is that both consist of carbon, hydrogen, and oxygen, but their monomers differ; carbohydrates are made of monosaccharides and lipids are made of fatty acids and glycerol (option b).
