Enzymes Flashcards
What is an enzyme?
Biological catalyst. Globular protein
Characteristics
-highly selective
-substrates into products
- proteins
The active site is
Where the substrate attaches
Binding site
Holds substrate in place
Catalytic site
Where reaction occurs
Specific sequence
●○○○○○●○○○○●
○○○● ●○○

Lock and key model
- active site has a rigid shape
- only substrate with matching shape can fit
Induced fit model
- flexible active site
- can change shape to accommodate
- bigger range of substrate specificity
Naming enzymes
End in ase after substrate they act on
Protease- uses
Pre digest protein during manufacturing baby foods
Lipase- use
Used with protease
Biological detergents to break down
Stains to smaller water soluble substances
Carbohydrase- use
Convert starch syrup, e.g, sports drinks
Isomerase- use
Glucose syrup to fructose
EC 1
Oxidoreductases
EC2
Transferase
