What non-competitive inhibition means in Biology A-Level, as defined for AQA.
Definition of non-competitive inhibition
Check what you remember
Read the wording for your board, then hide it and explain non-competitive inhibition in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
An inhibitor binds to an allosteric site, changing the active site shape so fewer enzyme-substrate complexes form; this inhibition is typically reversible.
