By the action of enzymes, the rate of biochemical reaction

Options

A. Does not change
B. Increases
C. Decreases
D. Either (1) or (3)

Answer

**Step-by-Step Solution:**

1. **Understanding Enzymes**: Enzymes are biological catalysts that facilitate biochemical reactions in living organisms. They are crucial for various metabolic processes.

2. **Role of Enzymes**: Enzymes work by lowering the activation energy required for a reaction to occur. Activation energy is the minimum energy needed for a chemical reaction to take place.

3. **Effect on Reaction Rate**: By lowering the activation energy, enzymes increase the likelihood of reactants colliding with enough energy to react. This results in an increased rate of the biochemical reaction.

4. **Conclusion**: Therefore, the action of enzymes leads to an increase in the rate of biochemical reactions.

5. **Final Answer**: The correct option is **B: increase**.
