  • competitive inhibitors
    • Competitive inhibitors work in the following ways
      • a molecule or part of, that has a similar shape to that of the substrate of the enzyme can fit into the active site of the enzyme
        • this blocks the substrate from entering the active site preventing the enzyme from catalysing the reaction
          • the enzyme cannot carry out its function and is said to be inhibited
            • the non substrate molecule that binds to the active site is a type of inhibitor.
              • substrate and inhibitor molecules present in a solution will compete with each other to bind to the active sites of the enzymes catalysing the reaction
                • which reduced the number of substrate molecules bonding to active sites in a given time and slow down the rate of reaction
                  • because of this such inhibitors are called competitive inhibitors
