ENZYMES
Active Site
-
-
An enzyme has a dent called the active site .This shape is complimentary to the shape of the substrate
The substrate fits into the active site of the enzyme, forming a enzyme substrate complex
-
-
Properties of enzymes
-
- Enzymes are made inactive by high temperatures
-
-
As the temperature increases beyond this, the enzyme molecules start to lose their shape. The active site no longer fits perfectly with the substrate
- Enzymes work best at a particular temperature
-
-
-
- Enzymes work best at a particular pH
-
-
-
They can be used over and over again, so a small amount of enzyme can change a lot of substrate
-
-
Lock and key mechanism
An enzyme works by allowing the molecule of the substrate on which it is acting on to fit into it. The fit has to be perfect
