Question

1. what is activation energy, and why is it important in chemical reactions? 2. explain how enzymes affect the activation energy of a chemical reaction. then describe the benefit of this in living organisms.

Explanation:

1. Activation energy is the minimum energy required for a chemical reaction to occur. It is important as it determines the rate at which a reaction proceeds. A higher activation energy means fewer reactant molecules have enough energy to react, slowing the reaction.
2. Enzymes are biological catalysts that lower the activation energy of a chemical reaction. In living organisms, this allows reactions to occur at lower temperatures and more rapidly, which is essential for maintaining life processes such as metabolism, digestion, and cellular function.

Answer:

1. Activation energy is the minimum energy for a reaction. It's important as it affects reaction rate.
2. Enzymes lower activation energy. Benefit: Reactions occur at lower temps and faster, crucial for life processes.
