The characteristics of four proteins, W, X, Y and Z, are given below. W is made up of two polypeptides joined by disulfide bonds. X is made up of three polypeptides wound tightly around each other. Y is made up of four polypeptides, and each one has a prosthetic group. Z is made up of four polypeptides joined together by disulfide bonds. Which row correctly matches the named proteins?
