Textbook Question
Chapter 8, Problem 2P
The enzyme urease catalyzes the hydrolysis of urea to ammonia plus carbon dioxide. At 210C the uncatalyzed reaction has an activation energy of about 125 kJ/mol, whereas in the presence of urease the activation energy is lowered to about 46 kJ/mol. By what factor does urease increase the velocity of the reaction?
