Enzymes are _ in nature.
Correct answer: B. Proteins
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Vitamins
Explanation
Enzymes are primarily proteins that serve as biological catalysts, facilitating and accelerating biochemical reactions by lowering the activation energy required for those reactions. They are essential for various metabolic processes and are highly specific to the substrates they bind to.While carbohydrates, lipids, and vitamins play crucial roles in biological systems, they do not function as enzymes. Carbohydrates provide energy and structural support, lipids are involved in energy storage and membrane structure, and vitamins are essential micronutrients required for numerous physiological functions but do not act as catalysts in reactions.

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.
