Which of the following protein structures is exemplified by globular proteins?

Question

Quizplus · Accepted Answer

Globular proteins exhibit a tertiary protein structure, which involves the arrangement of secondary structures (e.g. alpha helices and beta sheets) into a compact, 3D shape. This structure allows globular proteins to function as enzymes, signaling molecules, and transport proteins among other roles. Globular proteins do not typically exhibit a quaternary structure, as this involves the interaction of multiple protein subunits to form a larger complex. Primary structure refers to the linear sequence of amino acids in a protein, while secondary structure refers to the localized folding patterns that result from hydrogen bonding between amino acids. Therefore, choices B, C, D, and E can be eliminated as incorrect.
