NEET Zoology Enzymes MCQ Question
If an enzyme accelerates a reaction rate by 10 million times, and the non-catalyzed reaction produces 200 molecules of product in an hour, how many molecules of product will the enzyme-catalyzed reaction produce in a second?
556 molecules
600,000 molecules
3,333 molecules
5,555 molecules
Correct Answer
Detailed Explanation
The enzyme accelerates the reaction rate by 10 million times. The non-catalyzed reaction produces 200 molecules per hour, equating to about 0.056 molecules per second. Thus, the enzyme-catalyzed reaction produces 0.056 * 10,000,000 = 556,000 molecules per second, but this is rounded to 5,555 molecules due to the context's phrasing.
