Enzymes: slow down a reaction as they are consumed. increase the amount of substrate needed for a reaction to occur. raise the activation energy needed for a reaction to occur. lower the activation energy needed for a reaction to occur. decrease the amount of substrate needed for a reaction to occur.

Enzymes accelerate a chemical reaction by a. reducing the amount of substrate produced. b. lowering the energy of activation of the reaction. c. increasing the energy of activation of the reaction. d. reducing the amount of reactant needed.
Enzymes are described as catalysts, which means that they provide activation energy for the reactions they facilitate increase the free energy of the reactants to make the reaction go faster are proteins increase the rate of a reaction without being consumed by the reaction can alter the free energy change (ΔG) for a chemical reaction
Marlyn J.
Enzymes (a) speed up reactions that would otherwise occur much more slowly. (b) spur reactions that would otherwise never occur. (c) provide energy for anabolic but not catabolic pathways. (d) are consumed during the reactions they catalyze.
