|
|
Active site |
An enzyme binds a substrate in a region |
|
|
Inhibitors |
substances that slow down or stop enzyme |
|
|
Competitive inhibitors |
Molecules that are very similar to the substrate, so they can bind to the enzyme but cant react |
|
|
Noncompetitive inhibitors |
Molecules that are not similar to the substrate and therefore do not bind to the active site |
|
|
Enzyme inhibitor |
Any substance that can reduce the rate of enzymatic reaction, but does not cause denaturation and inactivation of enzymes |
|
|
Irreversible inhibition |
Cased by the covalent binding of inhibitors with the essential groups of enzymes |
|
|
Reversible inhibition |
Caused by the non covalent binding of inhibitors with enzymes |
