Question

How do enzymes affect the reactions in which they take part?

A.Most enzymes slow down chemical reactions.
B.Enzymes decrease the activation energy of the reaction.
C.Enzymes increase the activation energy of the reaction.
D.Enzymes are converted into products in the reaction.

Answer 1

B. Enzymes decrease the activation energy of the reaction :)

Step-by-step explanation:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
