Answer:
The correct answer is: catalysts lower the activation energy of the reaction.
Explanation:
Catalysts are substances that in our bodies are commonly represented by enzymes (specialized proteins) and that are used in chemical reactions to speed them up.
In order to achieve this, catalysts lower the activation energy of chemical reactions, which is a value of energy that must be obtained for the reaction to actually happen.
Catalysts are constantly used in our bodies and are responsible for the proper functioning of every organ. These catalysts can be used over and over again because they are not consumed in the reaction.
