In an enzyme,the polypeptide chain folds into a compact shape known as the ________ structure.

Question

Quizplus · Accepted Answer

The tertiary structure refers to the three-dimensional shape of an enzyme that is formed by the folding of the polypeptide chain into a compact structure. This structure is important for enzyme function as it determines the active site where substrates can bind and chemical reactions can occur. The primary structure refers to the linear sequence of amino acids, the secondary structure refers to the local folding patterns of the polypeptide chain such as alpha-helices or beta-sheets, and the quaternary structure refers to the arrangement of multiple protein subunits in a larger protein complex.
