Enzymes are biological catalysts that speed up a reaction by _ the activation energy.
Correct answer: C. Decreasing
- A. Maintaining a constant
- B. Increasing
- C. Decreasing
- D. None of these
Explanation
One of the primary functions of enzymes is to lower the activation energy required for a chemical reaction to occur. Activation energy is the energy barrier that must be overcome for a reaction to proceed. By lowering this barrier, enzymes facilitate and accelerate reactions that might otherwise occur too slowly under physiological conditions.

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.
