Final answer:
An energy diagram illustrates the difference between a catalyzed reaction and an uncatalyzed reaction. In a catalyzed reaction, the energy diagram will show a lower activation energy compared to an uncatalyzed reaction. Enzymes lower the activation energy and speed up chemical reactions in living organisms.
Step-by-step explanation:
An energy diagram illustrates the difference between a catalyzed reaction and an uncatalyzed reaction. In a catalyzed reaction, the energy diagram will show a lower activation energy compared to an uncatalyzed reaction. The activation energy is the energy required to start a chemical reaction.
In the energy diagram of a catalyzed reaction, the reactants start at a higher energy level, and the enzyme lowers the activation energy, making it easier for the reaction to occur. As a result, the products are formed more quickly. The energy diagram for an uncatalyzed reaction will show a higher activation energy, indicating that the reaction is slower and requires more energy to proceed.
By providing an alternative reaction pathway with a lower activation energy, enzymes speed up the rate of chemical reactions in living organisms.
