  Biological catalysts
• Enzymes


  • They function in living systems
  • They speed up the rate of chemical reactions without being used up or changed
• Enzymes


  Globular proteins

  Globular proteins
• Enzymes


  • Critical to their function is the active site where the substrate binds
• Metabolic pathways


  Controlled by enzymes in a biochemical cascade of reactions
• Enzymes


  • Critical to their function is the active site where the substrate binds
• Virtually every metabolic reaction within living organisms is catalysed by an enzyme – enzymes are therefore essential for life to exist

  Controlled by enzymes in a biochemical cascade of reactions
• Intracellular enzymes


  Produced and function inside the cell
• Virtually every metabolic reaction within living organisms is catalysed by an enzyme – enzymes are therefore essential for life to exist
• Extracellular enzymes


  Secreted by cells and catalyse reactions outside cells (eg. digestive enzymes in the gut)
