Enzymes
- definition: a biological catalyst
(causing change/ to start), that
speeds up chemical reactions by
lowering the amount of activation
energy
- enzymes are protiens (amino
acids)
- every enzyme is specific for a
specific chemical reaction /
substrate
- Substrate: the
reactants an
enzyme works on
- Substrate: the
reactants an
enzyme works on
- -ase
- Substrate/enzyme
lactose/lactase
sucrose/sucrase
carbonic acid/carbonic
anhydrase
- Substrate/enzyme
lactose/lactase
sucrose/sucrase
carbonic acid/carbonic
anhydrase
- every enzyme is specific for a
specific chemical reaction /
substrate
- Lock and key method
- Lock: enzyme
key: substrate
- enzyme + substrate --> Enzyme
substrate compex --> enzyme +
product
- enzymes are not used up or destroyed; they are
at the begining and the end of the chemical
reaction
- enzymes are not used up or destroyed; they are
at the begining and the end of the chemical
reaction
- Lock: enzyme
key: substrate
- Optimal Conditions for enzymes
- specific temperatures and pH's
- Denature: lose its
function due to
change of shape
- When an enzyme is at the
wrong temperature and pH, it
denatures (breaks down) and
loses its conformation (shape)
- Result: the substrate can not fit into
the active sight --> no product is
made
- Result: the substrate can not fit into
the active sight --> no product is
made
- specific temperatures and pH's
