Enzymes cont.
•the presence of
inhibitors.
–competitive inhibitors are molecules that bind to the same site as
the substrate - preventing the substrate from
binding as they do so - but are not changed by the enzyme.
–noncompetitive inhibitors are molecules that bind to some other
site on the enzyme reducing its catalytic power.
•pH. The conformation
of a protein is influenced by pH and as enzyme
activity is crucially dependent on its conformation,
its activity is likewise affected.
