41. Enzymes belong to which class of biomolecules?

  • A. Carbohydrates
  • B. Lipids
  • C. Proteins
  • D. Nucleic acids

Explanation: Almost every enzyme is a globular protein whose precisely folded tertiary structure creates the active site, which is why heat and extreme pH destroy catalytic power.

Correct answer: Proteins
