- Enzymes are globular proteins that act as biological catalysts.
- Most enzymes are named after the reaction they catalyse and the name ends in ase.
- Enzymes are more efficient and faster acting catalysts than most laboratory or industrial catalysts.
- Most enzymes are unique to a particular biochemical reaction.
- Enzyme operation is often pH and temperature dependent.
Enzymes usually function over a narrow range of temperature and pH.
- Enzymes are believed to work in two ways:
⚛ induced fit
⚛ lock and key
- Enzymes can be denatured by changes in temperature or pH.
- Denaturation refers to the disruption of the tertiary and secondary structure of the enzyme preventing it from acting as a catalyst.
Denaturation does NOT effect the primary structure of an enzyme.
