      hiya can any1 help i’m confused in "zonia world "again – right here goes……….. for enzyme reactions theres lock & key where the enzyme’s active site is specific for a specific substrate and induced fit model where the enzyme’s active site shape alters to fit the appriopriate substrate am i right so far? so is each type of enzyme a specific model either lock&key or induced fit????????? if so does any1 know which catalase is please 😕 hope that makes sense because i don’t xxx thank-you 🙂

      Enzymes are very specific.
      In the lock&key model, an enzyme has a particular shape into which the substrates fit exactly so that the enzyme and substrate fit together as a lock and key.

      In the induced fit model, enzymes have flexible structures. The active site of an enzyme can be modified as the substrate interacts with the enzyme.

      Each enzyme has a name that usually indicates exactly what it does, and often ends in "ase". Ex: catalase, lactase, caspase, protease, lipase …

      Catalase is an common enzyme found in living organisms. Its structure consists of a tetramer of 4 polypeptide chains. It also can convert hydrogen peroxide to water and oxygen. That’s all i know.
      Peace, 🙂

      😆 your a bad sod Zonia i dont know what r u like, Then again we all cant be top of the class like some eh

      I found out the answer the induced fit model is just the latest theory concerning how enzyme-substrate complexes form thank-you for your help especially you 92 😕
