3. Usually an enzyme acts only on a specific molecule
(substrate), by first
forming an enzyme-substrate complex, then breaking down into
products
and regenerating the enzyme.
4. Enzymes must be activated before they have the
ability to function as a
catalyst.
5. Only a small part of the enzyme molecule acts on
the substrate. This part of
the enzyme is referred to as the active site.
6. Enzymes can be inhibited when other substances
block the active site.
1. pH
2. Chemical kinetics, especially the effects of
temperature on reaction rates
(see Reaction Rates module)
3. Characteristics of proteins
4. Structure of proteins
5. Denaturation of proteins
1. Collect and plot data on a graph.
2. Interpret a graph.
3. Measure temperature.
4. Work with general laboratory glassware.
5. Set up apparatus to collect gas by displacement of
water.
