What effects are produced by an enzyme on the general reaction below? Select all that apply. S = P The formation of the transition state is promoted. The activation energy for the reaction is lowered. The concentration of the products is increased. The reaction equilibrium is shifted toward the reactants. AG for the reaction decreases. The rate constant for the reverse reaction (k) increases. What effects are produced by an enzyme on the general reaction below? Select all that apply.
