Enzymes belong to which class of biomolecules?
Correct answer: C. Proteins
- 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. The one exception is the small group of catalytic RNA molecules called ribozymes, which is why nucleic acids are offered here. Carbohydrates and lipids never act as catalysts.

About Characteristics of Enzymes
Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
