big ninja


Essential Idea:

Enzymes control the

metabolism of the cell

     
Understandings:

  • Enzymes have an active site to which specific substrates bind
  • Enzyme catalysis involves molecular motion and the collision of substrates with the active site
  • Temperature, pH and substrate concentration affect the rate of activity of enzymes
  • Enzymes can be denatured
  • Immobilized enzymes are widely used in industry


Applications:

  • Methods of production of lactose-free milk and its advantages


Skills:

  • Design of experiments to test the effect of temperature, pH and substrate concentration on the activity of enzymes
  • Experimental investigation of a factor affecting enzyme activity
