enzymes do not have a purpose in living things

Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-2: -The process by which it increases the rate of a reaction by lowering its activation energy is called catalysis.
Detailed explanation-3: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
Detailed explanation-4: -The correct answer is A) the activation energy. Enzymes speed up chemical reactions by lowering the activation energy.
