Which component decreases the activation energy of a chemical reaction?
BabaBlast [244]

Answer:

Presence of an enzyme

Explanation:

Enzymes are the biomolecules present in cells. The enzymes serve to catalyze the chemical reactions that occur inside the cells. Enzymes speed up the rate of the chemical reaction and allow the formation of products at a fast rate. This is done by lowering down the activation energy that is required to begin a chemical reaction. This energy breaks down the older bonds present in substrates so that new bonds can be formed. Enzymes lower down the activation energy to speed up the reactions.
