WebCatalysis (/ k ə ˈ t æ l ə s ɪ s /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈ k æ t əl ɪ s t /).Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and … WebEnzymes, like catalase, are proteins that speed up chemical reactions by reducing the amount of energy the reaction needs to take place.Specifically, an enzyme reduces the activation energy needed to …
