Question

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 (k_reverse)_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

(k_reverse)_enzyme = 4.0 × 10^-4 sec^-1

(k_reverse)_enzyme = 1.1 × 10^-2 sec^-1

(k_reverse)_enzyme = 0.18 sec^-1

(k_reverse)_enzyme = 2.8 sec^-1

(k_reverse)_enzyme = 2.5 × 10³ sec^-1
