- Protein molecules help cells carry out many of their functions, and they are part of body structures such as hair and nails.
- Protein molecules are part of body structures such as hair and nails, but they do not help cells carry out many of their functions.
- Protein molecules help cells carry out many of their functions, but they are not part of body structures such as hair and nails.
- Protein molecules do not help cells carry out many of their functions, and they are not part of body structures such as hair and nails.
