The enzyme increases the rate of reaction by which of the following?
Correct answer: D. Decreasing activation energy.
- A. Decreasing kinetic energy.
- B. Decreasing chemical energy.
- C. Decreasing potential energy.
- D. Decreasing activation energy.
Explanation
Enzymes increase the rate of a chemical reaction by lowering the activation energy required for the reaction to proceed. The activation energy is the energy barrier that must be overcome for a chemical reaction to occur. By lowering this barrier, enzymes facilitate the conversion of reactants into products at a faster rate than would occur in the absence of the enzyme.

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.
