Which of the following BEST describes the relationship between concentration and enzyme activity?
A. As enzyme concentration decreases, enzyme activity increases.
B. When substrate concentration decreases, enzyme activity decreases.
C. As substrate concentration increases, substrate activity increases.
D. When substrate concentration increases, enzyme activity decreases.

Respuesta :

The statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B).

  • Enzymes are proteins that speed up chemical reactions by lowering the activation energy of that reaction.

  • Some factors that alter enzymatic activity include temperature, pH, and substrate concentration.

  • An enzyme works in optimum condition as long as there is more substrate available which can be broken down by the specific enzyme.

  • However, the enzymatic activity increases as the substrate concentration until a limiting value is reached.

In conclusion, the statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B is correct).
