Question

I need to know the formula being used to solve this and exact steps on how to solve. I already know the answer is B.

Answer questions 17 to 21 based on the following information. The enzyme urease catalyzes the decomposition of urea into ammonia and CO2. The following values of urease have been determined at 10 nM total enzyme concentration, i.e., [E]T = 10 nM. KM = 25 µM; kcat = 1x104/s Hint: 1 µM = 10-6 M; 1 nM = 10-9 M 17) The Vmax of urease in this measurement is ___. A) 1.0 x 104 M/s B) 1.0 x 10-4 M/s C) 1.0 x 104 /s D) 1.0 x 1012 M/s E) 1.0 x 10-5 M/s

Explanation / Answer

Answer: Option B is correct.

Explanation:

Kcat = Vmax/[E]

Vmax = Kcat X [E]

= 104 X 10 X 10-9

= 10 X 10-5

= 1 X 10-4 M/s
