Place each picture in the correct category

The image shows four diagrams illustrating the levels of protein structure: primary, secondary, tertiary, and quaternary. Each level is depicted with a unique representation:

1. **Primary Structure**: This diagram shows a linear sequence of amino acids, represented by different colored circles connected by lines, indicating the peptide bonds between them.

2. **Secondary Structure**: This diagram illustrates common structural motifs such as alpha helices and beta sheets. It displays folded patterns, often shown as spirals or arrows indicating directionality and connections within the protein chain.

3. **Tertiary Structure**: This diagram represents the overall 3D structure of a single protein molecule, demonstrating how the secondary structures are further folded and packed into a complex shape. It showcases specific interactions like disulfide bridges.

4. **Quaternary Structure**: This diagram depicts a complex of multiple protein molecules or subunits assembling into a functional protein. It highlights how different units interact and fit together in a larger structure.

These diagrams collectively explain the hierarchical organization of proteins from simple sequences to complex structures.
