What level of protein structure is associated with its function?

Question

Quizplus · Accepted Answer

The tertiary structure of a protein is associated with its function. This is because the tertiary structure determines the 3-dimensional shape of the protein, which in turn determines its unique function. The primary structure (A) is simply the linear sequence of amino acids, while the secondary structure (B) refers to local folding patterns such as alpha helices and beta sheets. The quaternary structure (D) is only relevant for proteins that have multiple subunits. "Binary" (E) is not a recognized level of protein structure.
