Resource summary

Enzymes
  1. definition: a biological catalyst (causing change/ to start), that speeds up chemical reactions by lowering the amount of activation energy
    1. enzymes are protiens (amino acids)
      1. every enzyme is specific for a specific chemical reaction / substrate
        1. Substrate: the reactants an enzyme works on
        2. -ase
          1. Substrate/enzyme lactose/lactase sucrose/sucrase carbonic acid/carbonic anhydrase
        3. Lock and key method
          1. Lock: enzyme key: substrate
            1. enzyme + substrate --> Enzyme substrate compex --> enzyme + product
              1. enzymes are not used up or destroyed; they are at the begining and the end of the chemical reaction
            2. Optimal Conditions for enzymes
              1. specific temperatures and pH's
                1. Denature: lose its function due to change of shape
                  1. When an enzyme is at the wrong temperature and pH, it denatures (breaks down) and loses its conformation (shape)
                    1. Result: the substrate can not fit into the active sight --> no product is made
