A binding site on a protein is

Question

Quizplus · Accepted Answer

A binding site on a protein is an area of the protein with a shape complementary to that of a ligand, and this shape is determined by the amino acid sequence of the protein. Therefore, option D is the best choice as it includes both of these characteristics. Option A is not complete because it only describes the shape of the binding site but doesn't mention the role of amino acid sequence. Options B and C are incorrect because the presence and location of binding sites are not necessarily determined by the amino acid sequence of the protein or by regions of amino acids that must be adjacent to each other on a polypeptide chain. Option E is incorrect because not all of the choices are correct.
