|
What is an inhibitor
|
it reduces catalytic activity
|
|
|
What is an activator
|
it allows catalytic activity
|
|
|
What is feedback inhition
|
The last product in a metabolic pathway binds to an allosteric site of an enzyme in an early step of the pathway and inhibits activity of the enzyme
|
|
|
What is irreverisible inhibition
|
the enzyme is permanently inactivated or destroyed
|
|
|
What is reversible inhibition
|
if the inhibitor is removed, the enzyme activity can be recovered
|
|
|
What is competitive inhibition
|
The inhibitor is similar in structure to a substrate. it competes with sub for binding to the active site and adding more sub does help
|
|
|
What is noncompetitive
|
binds at allosteric site, alters enzyme shape to make active site unavailable and adding more sub. doesn't help
|
|
|
What is oxidoreduclasses
|
catalyze ox/red. rxn
|
|
|
What is transferases
|
transfers a functional group
|
|
|
What is hydrolases
|
it catalyze the hydrolysis of various bonds
|
|
|
What is lyases
|
it cleaves various bonds by means other than hydrolysis and ox.
|
|
|
What are the isomerases
|
it catalyzes isomerization changes within a single molecule
|
|
|
What is a ligase
|
it joins 2 molecules with covalent bonds
|
|
|
What plus a cofactor equals an active enzyme (bound together)
|
apoenzyme
|
|
|
What is the induced fit
|
When the enzyme-substrate complex forms, the shape changes.
