Question

Identify the correct statement from the following?

• A. The reaction rate is equal to the maximum velocity and is independent of the substrate concentration. The reaction is zero-order kinetics.
• B. The reaction rate is equal to the maximum velocity and is independent of the substrate concentration. The reaction is first-order kinetics.
• C. The reaction rate is lower to the maximum velocity and is independent of the substrate concentration. The reaction is second-order kinetics.
• D. The reaction rate is highr than the maximum velocity and is independent of the substrate concentration. The reaction is zero-order kinetics.

Answer 1

The correct option is A

The reaction rate is equal to the maximum velocity and is independent of the substrate concentration. The reaction is zero-order kinetics.

Two 20th century scientists, Leonor Michaelis and Maud Leonora Menten, proposed the model known as Michaelis-Menten Kinetics to account for enzymatic dynamics. The model serves to explain how an enzyme can cause kinetic rate enhancement of a reaction and explains how reaction rates depends on the concentration of enzyme and substrate. It explains that the rate is equal to the maximum velocity and is independent of the substrate concentration. The reaction is zero-order kinetics.
