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
