Metabolic Pathways Overview · NCERT Biology

Why are metabolic pathways usually enzyme-catalyzed?

  1. To increase randomness of reactions
  2. To enable reactions under normal cellular conditions
  3. To consume enzymes during the process
  4. To stop all spontaneous chemical reactions
Show answer and explanation

Correct answer: To enable reactions under normal cellular conditions

Enzymes allow reactions to proceed rapidly at normal cellular temperature and pH. Without enzymes, most reactions would be too slow.
