    Definition of Oxygen dissociation curve and the Bohr shift

    Check what you remember

    Read the wording for your board, then hide it and explain Oxygen dissociation curve and the Bohr shift in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: OCR

    Affinity changes with pO₂ to give the S-shaped oxygen dissociation curve, and a high pCO₂ lowers affinity further, increasing oxygen release where respiration is greatest.
