Enzyme inhibition

Question 1

Irreversible inhibition

Answer 1

-> Combines with the enzyme by permanent covalent bonding to one of the groups vital for catalysts to occur.
-> Occurs more slowly, its effects are more devastating.

Question 2

Reversible inhibition

Answer 2

-> When the inhibitor is removed enzyme can function normally again.
-> Competitive inhibition & non-competitive inhibition.

Question 3

Competitive inhibition

Answer 3

A competitive inhibitor binds to the active site of the enzyme, preventing the substrate from binding.

Question 4

Non-competitive inhibition

Answer 4

Binds to the enzyme at a site other than the active site, changing the shape of the active site and preventing the substrate from binding.
