Question

14. [6 pts) Indicate which of the following statements is True (T) or False (F) When water interacts with hydrophobic molecules, it becomes more ordered and entropy of the system increases The hydrophobic effect is predominant in protein stability The Ramachandran ploy shows combinations of dihedral angles in a polypeptide chain. A proteins function is directly related to the protein's secondary structure. The B sheet is primarily stabilized by R group interactions Clusters of secondary structures are motifs Domains and motifs depend on primary structure but only domains are repetitive super secondary structures. 2, 3 BPG is an allosteric modulator Enzymes are consumed during reactions In terms of protein-ligand binding, the larger the Ka, the greater the affinity Hemoglobin and myoglobin are heterotetramers Enzymes lower the binding energy for the reactions they catalyze Myoglobin contains two heme group The globin chains of myoglobin and hemoglobin prevent the oxidation of Fe2+ and Fe3+, which irreversibly binds oxygen The cooperativity of oxygen binding in hemoglobin arises from a shorter Fe-O, bond length in the T state compared to the R state In the binding of oxygen to myoglobin, the relationship between the concentration of oxygen and the fraction of binding sites occupied can best be described as hyperbolic In terms of protein-ligand binding, the larger the Ka, the smaller the Kd The tertiary structure of myoglobin is similar to that of a subunit of hemoglobin The quaternary structure of myoglobin is similar to that of a subunit of hemoglobin Oxygen binding to myoglobin is allosteric but not cooperative Fibrous proteins are primarily composed of nonpolar amino acids Superfamilies are the result of little similarity in amino acid sequence but similar functionality Oxygen is a heterotropic modulator of oxygen binding to hemoglobin I Keratin is composed of two right handed helices twisted in a left-handed superman
