Which of the following statement is true regarding enzyme inhibition?
It may be reversible but never irreversible
Reversible inhibitor may compete with substrate to bind at enzyme’s allosteric site
Irreversible inhibitor can bind to active site, allosteric site or any part of enzyme resulting permanent
damage
Non-competitive inhibition can be overcome by increasing substrate concentration
Give one similarities between competitive inhibitor and non-competitive inhibitor action
Both caused enzyme's conformation changed
The maximum rate of reaction is not reached
Reaction becomes slower
The rate of reaction can be increased by increasing the substrate concentration
Which statements is about competitive inhibitor?
Binds to the allosteric site of enzyme
Binds permanently to the enzyme
The effect of enzyme can be overcome by adding more substrates
It will cause denaturation of enzyme
Which of these statements are true about competitive inhibitor?
Inhibitor and substrate has similar structure
The inhibitor binds to the allosteric site
The conformation of active site changed due to the inhibitor
Quantity of product formed is the same as reaction with inhibitor
what impedes enzymatic reactions by binding to another part of the enzyme?
noncompetitive inhibitor
competitive inhibitors
