What is the rate enhancement as a result of the presence of an enzyme if the uncatalyzed rate of the reaction is 1.2 10² mmol/sec and the catalyzed rate is 2.4 10⁴ mmol/sec? A) 0.005 B) 200 C) 2.88 10⁶ D) 2

Question

Quizplus · Accepted Answer

The rate enhancement as a result of the presence of an enzyme is given by:
Rate enhancement = Catalyzed rate / Uncatalyzed rate
Substituting the given values:
Rate enhancement = 2.4 mmol/sec / 1.2 mmol/sec
Rate enhancement = 2
Therefore, the rate enhancement is 2, which means the reaction occurs 2 times faster in the presence of the enzyme. The correct answer is B.
