To examine: Whether the statement, “The role of ATP hydrolysis in actin
Introduction: The actin filaments are the helical
Answer to Problem 1P
Correct answer: The statement is true.
Explanation of Solution
When ATP and GTP in actin filaments and in microtubules are hydrolyzed respectively, much of the free energy released. This is due to the cleavage of high-energy bond that is stored in the polymer lattice. The free energy of the ADP or GDP containing polymer is higher than that of the ATP or GTP containing polymer. Thus, the equilibrium shifts towards depolymerization.
Hence, the statement is true.
