Explain how the structures of lipids, carbohydrates, proteins, and nucleic acids relate to their cellular roles.
Answer
Lipids are largely hydrocarbon-based, poorly soluble in water, and contribute to membranes and energy storage. Carbohydrates contain many hydroxyl groups, are generally water-soluble, and can provide energy or structural material. Proteins are amino-acid polymers whose sequence influences their properties. Nucleic acids are nucleotide polymers that store or convey genetic information.
Explanation
The material connects molecular composition to biological role. Hydrophobic lipids are suited to membranes and energy storage; carbohydrate hydroxyl groups contribute to water solubility; amino acid sequence shapes protein properties; and nucleotide sequences encode or transmit genetic information. **Key takeaway:** Molecular structure helps determine cellular function. **Glossary:** Polymer: molecule made from repeating units.
