Multiple choice

The Michaelis-Menten equation describes the relationship between the reaction rate and substrate concentration in enzyme kinetics. What is the mathematical expression for this equation?

  1. $v = k_m[S] / (K_m + [S])$
  2. $v = k_m[S] / (K_m - [S])$
  3. $v = k_m[S] / ([S] - K_m)$
  4. $v = k_m[S] / (K_m + [S]^2)$

A Correct answer
Explanation

The Michaelis-Menten equation is given by $v = k_m[S] / (K_m + [S])$, where $v$ is the reaction rate, $k_m$ is the maximum reaction rate, $[S]$ is the substrate concentration, and $K_m$ is the Michaelis constant.
