Webb23 okt. 2024 · Proteins are built in the cell by ribosomes. Ribosomes are small organelles that are found in the cytoplasm of the cell. They are made up of two subunits, the large subunit and the small subunit. The large subunit is responsible for binding to the mRNA, and the small subunit is responsible for catalyzing the peptide bond formation. What is … Webb27 maj 2024 · Proteins, which are composed of amino acids, serve in many roles in the body (e.g., as enzymes, structural components, hormones, and antibodies).
