Answer 1

Here’s the completed table with the additional information regarding nucleic acids and a clearer alignment of functions and examples:

| Macromolecule | Function | Monomer | Examples |
|------------------|-----------------------------------|------------------|---------------------------------------|
| Carbohydrates | Short-term energy, structural support | Monosaccharides | Glucose, Fructose, Cellulose |
| Lipids | Long-term energy, cellular structure, signaling | Glycerol with fatty acids | Oils, Fats, Steroids |
| Proteins | Structural support, immunity, catalysts | Amino acids | Enzymes, Antibodies, Keratin |
| Nucleic acids | Stores genetic information, gene expression | Nucleotides | DNA, RNA |

### Key Points:
- **Carbohydrates** provide quick energy and can serve structural roles (like cellulose in plant cell walls).
- **Lipids** are essential for long-term energy storage and are vital in forming cell membranes, and also play roles in signaling (like steroids).
- **Proteins** serve numerous functions, including acting as enzymes to catalyze biochemical reactions, forming structures, and providing immune responses.
- **Nucleic acids** (DNA and RNA) are crucial for storing and transmitting genetic information, as well as for the synthesis of proteins.
