Some proteins, like hemoglobin or antibody molecules, require multiple polypeptide chains to come together to act as a single protein. If the association among the different polypeptide chains is blocked, the ________ structure of the protein is destroyed.

Question

The quaternary structure is the arrangement of multiple polypeptide chains or subunits to form a functional protein. If the association among these chains is blocked, the quaternary structure will be destroyed, leading to the loss of protein function. The primary, secondary, and tertiary structures only involve a single polypeptide chain and would not be affected by the association among different polypeptide chains. "Binary" is not a relevant term in protein structure.
