What is the primary function of enzymes?

  1. Holding genetic information

  2. Regulating metabolic processes

  3. Breaking down molecules

  4. Transcribing genetic information

The correct answer is: Breaking down molecules

Enzymes are responsible for catalyzing biochemical reactions by breaking down molecules into smaller compounds. Option A is incorrect because holding genetic information is the function of nucleic acids, not enzymes. Option B is incorrect because while enzymes play a role in regulating metabolic processes, their primary function is breaking down molecules. Option D is incorrect because transcribing genetic information is the function of another group of enzymes called RNA polymerases.
