You discover an enzyme that catalyzes the following reaction, S ⇌ P.

Given the following table of data, what is the rate constants for conversion of P to S, in the presence and absence of the enzyme. What is the rate constant for enzyme-catalyzed conversion of P to S, called the (kreverse)enzyme?

  Uncatalyzed

(no enzyme)

   kforward = 1.8 sec-1

kreverse = 2 × 10-3 sec-1

Catalyzed

(enzyme present)

  kforward = 2.5 × 103 sec-1

 kreverse =  ?

Group of answer choices

(kreverse)enzyme = 4.0 × 10-4 sec-1

(kreverse)enzyme = 1.1 × 10-2 sec-1

(kreverse)enzyme = 0.18 sec-1

(kreverse)enzyme = 2.8 sec-1

(kreverse)enzyme = 2.5 × 103 sec-1
