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:

a. Enzymes are biological catalysts that speed up chemical reactions. They lower the activation - energy barrier for the reaction to occur more readily.
b. Enzymes reduce the activation energy required for a chemical reaction to start. This makes it easier for reactant molecules to reach the transition state and proceed with the reaction.
c. The term "catalyzed" means that a catalyst (in this case, an enzyme) is present to increase the rate of a chemical reaction by lowering the activation energy.

Answer:

a. It speeds up the reaction.
b. It lowers the activation energy.
c. It means a catalyst (enzyme) is present to increase the reaction rate by lowering activation energy.
