What Non-competitive inhibitors means in Biology A-Level, as defined for OCR.
Definition of Non-competitive inhibitors
Check what you remember
Read the wording for your board, then hide it and explain Non-competitive inhibitors in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
These bind at a site other than the active site, changing the shape of the active site so the substrate can no longer bind, and adding more substrate does not overcome this.
