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