Correct answer: D. Globular proteins
- A. Fibrous proteins
- B. Lipoproteins
- C. Low molecular weight proteins
- D. Globular proteins
Explanation

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
