Be sure to answer all parts Urea, (NH2)2CO, is used as a nitrogen release fertilizer; many soil bacteria contain the enzyme urease, which catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The Michaelis constant, KM, for urease is 2 × 10−3 M and k2 = 2.5 × 104 s−1 under a specific set of conditions. (a) Calculate the...
