Human hemoglobin protein is composed of four separate polypeptide chains (subunits) that are bound together to form the hemoglobin protein. Each of the polypeptide chains has alpha-helices and beta-pleated sheets. The alpha-helices and beta-pleated sheets represent_____protein structure while the highest structural level for the protein is ____. Group of answer choices secondary; quaternary tertiary; quaternary secondary; tertiary tertiary; tertiary primary; tertiary

The following molecular diagram represents the protein hemoglobin. Hemoglobin is an oxygen-carrying protein found in red blood cells. Hemoglobin is made from 4 polypeptide chains interacting together. The interaction of these 4 polypeptide chains is an example of a: - Primary protein structure - Secondary protein structure - Tertiary protein structure - Quaternary protein structure
