Question

Tobin performed an experiment in which he mixed varying amounts of enzyme with an excess amount of substrate. He measured the rate of each reaction and recorded his data in the table below. What can Tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?

A. The experiment is invalid because it was performed in the presence of excess substrate.

B. There is an inverse relationship; as the enzyme concentration increases, the reaction rate decreases.

C. There is no relationship between the enzyme concentration and the reaction rate.

D. There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.

Answer 1

D. Basically as the left column increases, the right column increases.

Answer 2

D. There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
