Question

1. using figure 1, how does using an enzyme in a chemical reaction impact the reaction?

a. does it speed up or slow down the reaction?
b. how does the enzyme impact activation energy?
c. based on your answers to questions a and b, what do you think the term “catalyzed” means?

Explanation:

Enzymes are biological catalysts. They increase reaction rates by reducing the energy barrier (activation energy) needed for the reaction to occur. The term "catalyzed" refers to a reaction being influenced by a catalyst to proceed more quickly.

Answer:

a. It speeds up the reaction.
b. It lowers the activation energy.
c. "Catalyzed" means a reaction is facilitated by a catalyst (in this case, an enzyme), which speeds up the reaction by lowering the activation - energy.
