Urease Is an Enzyme That Catalyzes the Decomposition of Urea

question 23

Short Answer

Urease is an enzyme that catalyzes the decomposition of urea to ammonia and carbon dioxide. The rate constant for the uncatalyzed reaction is 4.0  10^-11/s at 22°C. Urease increases the rate constant to a value of 8.0  10^-5/s. Use the Arrhenius equation, which is given below, to determine the difference in the activation energies E_uncatalyzed - E_catalyzed. (R = 8.315 J/mol K)
