Question

34. In the enzyme reaction above, catechol is the substrate, oxygen is a reactant, catechol oxidase is the enzyme, benzoquinone is the product, and water (H2O) is a by-product. Which of the following will decrease the rate of this reaction?

A. Reducing the amount of oxygen
B. Reducing the amount of catechol
C. Increasing the amount of catechol oxidase
D. Increasing the amount of benzoquinone

I believe it's B but I'm really not sure. Any help would be really appreciated!

Answer 1

I would go woth A. it is listed specifically as a reactant.

Answer 2

Answer: The correct answers are option A and B.

Explanation:

In the given reaction catechol is a substrate and the oxygen is a reagent. The enzyme catechol oxidase acts on the substance and the then it reacts with the reagent oxygen.

The rate of the reaction will depend ion the concentration of the substrate and the reagent . The rate does not depend on the product and also the catalyst.

Thus the reaction rate depends upon the catechol and the oxygen.

Hence, the correct answer is Option A and B.
