Enzymes

• Enzymes


  Catalyze chemical reactions, highly specific, unique active site, speed up metabolic reactions
• Substrate


  Molecule that binds to enzyme's active site, being converted or modified by enzyme-catalyzed reaction, specific to enzyme
• Enzyme Specificity


  Shape and fit, chemical properties, induced fit
• Enzyme Specificity and Mutation

  Point mutations, altering chemical properties, shape changes, loss of specificity
• Non-Specific Enzyme Mutations


  Loss of enzyme function, substrate-binding errors, competitive inhibition, evolutionary consequences
