Final answer:
ATP synthase and kinesin are proteins that share quaternary structure, undergo allosteric regulation, are comprised of amino acids, and have moving parts essential to their functions.
Step-by-step explanation:
ATP synthase and kinesin are proteins that indeed share several properties. Both of these proteins have a quaternary structure, meaning they are composed of multiple polypeptide chains. They undergo allosteric regulation, a process where the protein's function is regulated by the binding of an effector molecule at a site other than the protein's active site. Indeed, they are comprised of amino acids, which are the building blocks of all proteins. Furthermore, both ATP synthase and kinesin have moving parts that are critical for their functions: ATP synthase has parts that rotate during the synthesis of ATP, and kinesin has regions that 'walk' along microtubules to move cargo within cells.
