An enzyme increases the speed of a reaction:
Correct answer: B. By lowering the activation energy requirements.
- A. By adding activation energy requirements.
- B. By lowering the activation energy requirements.
- C. By decreasing the concentration of products.
- D. By increasing the concentration of products.
Explanation
Enzymes are biological catalysts that increase the rate of reaction by lowering the activation of the energy of the reactions. Enzymes facilitate chemical reactions by lowering the activation energy required for the reaction to occur. Activation energy is the minimum amount of energy that must be input to a chemical system before a reaction can take place.

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.
