topic 2.5:  Enzymes

Essential Idea:
  • Enzymes control the metabolism of the cell.

Enzymes

2.5U1:  Enzymes have an active site to which specific substrates bind.
2.5U2:  Enzyme catalysis involves molecular motion and the collision of substrates with the active site.
2.5U3:  Temperature, pH and substrate concentration affect the rate of activity of enzymes.
2.5U4:  Enzymes can be denatured.
2.5U5:  Immobilized enzymes are widely used in industry.

2.5A1:  Methods of production of lactose-free milk and its advantages.
2.5Skill1:  Design of experiments to test the effect of temperature, pH and substrate concentration on the activity of enzymes.
2.5Skill2:  Experimental investigation of a factor affecting enzyme activity (Prescribed Practical 3).


2.5NOS.  Experimental design-accurate, quantitative measurements in enzyme experiments require replicates to ensure reliability.
LIfe is wonderfully complicated.   Stay curious.  Be skeptical.    And above all, ask many questions!
