  • ENZYMES
    • Enzymes are biological catalysts that cannot be used up in a reaction.
    • The Enzyme Action-
    • Effect of pH
      • Too high/low- loses shape
      • Optimum Temperature- Stomach- pH2  Mouth-pH7
    • Effect of Temperature
      • As temperature increases, so does kinetic activity, so enzymes work more efficienly.
        • If temperature is too high, enzymes lose their shape and the substrate cannot fit into the active site. It becomes denatured.
          • Optimum Temperature- Temperature which enzyme works best
            • Humans- 37
  • The substrate fits on the active site of the enzyme.
    • The Enzyme Action-
    • The Substrate has a specific shape which exactly fits into the Active site of the Enzyme.
      • Lock and Key Model
      • The Substrate is either broken down/built up.
        • This forms a new product
  • Effect of pH
    • Too high/low- loses shape
    • Optimum Temperature- Stomach- pH2  Mouth-pH7
