The right answer is A) lower the activation energy of chemical reactions.
The enzyme accelerates the reaction without changing the steady state.
Enzymes lower the activation energy of the substrate.
Activation energy or free activation energy is the energy that must be absorbed by the reagents to break their bonds.
The reagents must reach an unstable transition state in which the bonds are more fragile and easier to break.
Even an exergonic reaction requires the absorption of energy to reach the transition state.
