Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.
