If you wanted to show the 3-dimensional shape of a protein, including all of the atoms composing it, you should use a. 2. if you wanted to show the general shape of a protein, along with some important functional details such as folds and coils, you should use a. 3. if you wanted to show the 3-dimensional shape of a protein, including the backbone structure, folds, and coils, you should use a. 4. if you wanted to show a generalized protein in which the focus is on the protein's function rather than its structure, you should use a. 5. if you wanted to show the 3-dimensional shape of a protein by showing the amino acid side chains and their interactions, you should use a.

1. The space-filling model is used when one wants to show the three-dimensional shape of a protein, comprising all of the atoms constituting it.  

2. A simplified diagram is used when one desires to show the general shape of a protein, along with certain essential functional details like coils and folds.  

3. A ribbon model is used when one desires to demonstrate the three-dimensional shape of a protein, comprising the backbone composition, coils, and folds.  

4. A simple shape is used when one desires to demonstrate a generalized protein in which the focus is on the function of the protein in spite of its structure.  

5. A wireframe model is used if one wants to demonstrate the three-dimensional shape of a protein by showing the amino acid side chains and their associations.
