The final three-dimensional shape of a single polypeptide is called its _____________ structure.
A)primary
B)secondary
C)tertiary
D)quaternary

Question

Quizplus · Accepted Answer

The tertiary structure is the final three-dimensional conformation of a single polypeptide chain that results from interactions between amino acid side chains and the environment. This structure determines the protein's overall function. The primary structure refers to the linear sequence of amino acids, while the secondary structure refers to local folding patterns such as alpha helices and beta sheets. The quaternary structure refers to how multiple polypeptide chains come together to form a larger protein complex.
