Enzymes

• Enzymes


  Biological catalysts that increase reaction rates, convert large insoluble molecules into small soluble ones
• Enzyme activity


  • Optimum temperature - peak at 37°C, decreases after optimum
  • Optimum pH - usually around 7, symmetrical on either side
• Optimum temperature


  The best temperature for an enzyme to work at
• Optimum pH


  The best pH for an enzyme to work at
• Effect of temperature on enzyme activity

  1. Enzyme rate increases as temperature increases until optimum temperature

  2. After optimum temperature, enzyme rate decreases due to denaturation
• Effect of pH on enzyme activity

  1. Enzyme works best at pH 7

  2. Enzyme activity decreases as pH moves away from 7 in either direction due to denaturation
