Ribosomes are the cellular structures responsible for protein synthesis and are primarily composed of structural proteins and ribosomal RNA (rRNA). The structural proteins help maintain the ribosome's integrity and ensure its proper functioning during translation, the process of converting messenger RNA (mRNA) into a polypeptide chain of amino acids.

While enzymatic proteins are essential for various biochemical reactions within the cell and synthetic proteins refer to proteins being synthesized, neither category accurately describes the proteins that make up ribosomes themselves. Histones, on the other hand, are proteins involved in packaging DNA in eukaryotic cells and are not found in ribosomes. Therefore, the correct identification of the proteins found in ribosomes as structural proteins is based on their role in providing the necessary architecture for ribosome function and stability during the translation process.
