Enzymes As Catalysts

When an enzyme is added to a reaction the energy of the reactants is:

When an enzyme is added to a reaction the energy of the products is:

The ∆G of a reaction is -66 kJ/mol. Addition of an enzyme to this reaction would:

The conversion of fructose 6-phosphate into fructose 1,6-bisphosphate has a K_eq value of approximately 310 when coupled to the hydrolysis of ATP. If phosphofructokinase was added to a reaction mixture of fructose 6-phosphate and ATP the K_eq value would now be:

When an enzyme is added to a reaction the rate of the reaction is:

Scientists attempting to study the impact of an enzyme first ran the reaction of interest until it reached equilibrium. It took approximately 12 minutes to for the reaction to reach equilibrium. They then repeated the same reaction under identical conditions in the presence of an enzyme. If the amount of products was measured at the 5 minute mark in both reactions then at this time point:

A student added an appropriate enzyme to an uncatalyzed reaction in an attempt to increase the concentration of products at equilibrium. Will this approach work?

When an enzyme is added to a reaction the energy of the transition state is:

The activation energy of a combustion reaction at 35 degrees Celsius was found to be 45.9 kJ/mol. If this reaction was carried out at the same temperature in the presence of an enzyme the new activation energy would be:
