Inhbitiors are defined as substances that
reduce the rate of reaction in a enzyme controlled reaction
1 of 10
Competitive inhibitor molecules have
similar shape to that of the substrate
2 of 10
Because the competitive inhibitor has a simialr shape to the substate means what
that they can occupy the active site forming enzyme-inhibitor complex
3 of 10
Why does Enzyme inhibition occur
because the inhibitor molecule is occupying an enzymes active site and substrate molecule cant enter
4 of 10
Non-Competitive molecules do not compete with
substrate molecules for a place in the active site
5 of 10
The attachment of the of a non-competitive inhibitor changes the shape of the
Active site
6 of 10
Changing the substrate concentration for a non-competitive inhibitor will
have no effect on this form of inhibition
7 of 10
In a competitive inhibition molecules compete for
active site
8 of 10
Most competivitve inhibitors
do not bind permanently to the active site
9 of 10
Most non-competitive inhibitors bind
permanently to enzyme molecule
