Urease catalysis the hydrolysis of urea to ammonia and carbon dioxide. The nonenzymatic hydrolysis at 21'C has an activation energy barrier of 30kcal/mol, whereas that for the enzymatic reaction is 11 kcal/mol.
(a) Calculate how much enzyme accelerates the reaction over the non-catalyzed reaction?
(b) Calculate the temperature that will be required for the non-enzymatic hydrolysis of urea to proceed as rapidly as the enzymatic hydrolysis at 21'C
(c) Can this temperature be reached in aqueous solution?
