Which of the following statements regarding the reversible binding of ligands to proteins is not true? Proteins generally bind only specific ligands. Sometimes, ligand binding causes conformational change of the protein. In proteins composed of multiple subunits, the conformational change in one subunit can lead to conformational change in other subunits. Protein-ligand interaction can be regulated by a third molecule. Proteins which have a large number of alpha helices are easier to regulate than those composed mainly of beta sheets. Which of the following proteins is used for oxygen storage? myoglobin ferritin hemoglobin antibody chymotrypsin Which of the following proteins is an enzyme? serotonin transporter cytokines actin chymotrypsin None of the above. Which force does nature use to hold a protein and its ligand together? hydrogen bond interaction electrostatic interaction hydrophobic interaction van der Waals interaction All of the above.
