If an enzyme is added to a solution where its substrate and product are in equilibrium, what will occur? a. Additional substrate will be formed. b. The reaction will change from endergonic to exergonic. c. The free energy of the system will change. d. Nothing; the reaction will stay at equilibrium.

Hi everyone here, we have a question that says adding an enzyme to an already occurring reaction has no effect on rate of reaction. The possible reason is slash are a subjects and products are equal. If our substrates and products are equal, we are at equilibrium and adding an enzyme will have no effect on the rate of the reaction. So A is true. Be the reaction is an equilibrium. Like we just said, if the reaction is the equilibrium, adding an enzyme will not have an effect on the reaction. So B is true. See enzymes are already higher than substrates. If we already have more enzymes, then we have substrates. Then adding more enzymes is not going to have an effect on the rate of the reaction because we already have more of them. So C. Is true. So our answer is D all of the above. Thank you for watching. Bye.
