Webb16 feb. 2024 · Catalysts: Catalysts always speed up a reaction. They are substances that participate in a chemical reaction by increasing the rate of reaction but are unchanged by the reaction itself. Catalysts act by lowering the activation energy or the distance to the transition state. Catalysts are vital in many biological reactions. WebbEnzymes can either speed up or slow down a chemical reaction. b. Enzymes are not used up during the reaction in which they are involved. c.
