Reason why enzyme speeds up reactions
Shape of active site
Can remove groups to form or break double bonds
A 3D, complementary pocket on enzyme that binds to substrate
All digestive enzymes belong to this class of enzymes
Induced fit model
Urease
Catalase
Lock & Key model
Catalyses oxidation reduction reactions, uses NAD or FAD
Example of a common name of an enzyme
Hydrolases
symbolizes exact fit
lowers activation energy
Oxido-reductases
determines specificity of the enzyme
active site
indicates that the enzyme active site is flexible
example of absolute specificity
Lyases
