WebJun 12, 2015 · Definition of the Bohr effect. In the absence of an official definition, at a basic level one can define the Bohr effect as: The decrease in the oxygen affinity of haemoglobin in the presence of low pH or high CO 2. This is the consequence of the changes in the pKa of different amino acid residues, which occurs as the result of the haemoglobin tetramer … WebThe Bohr Shift. Changes in the oxygen dissociation curve as a result of carbon dioxide levels are known as the Bohr effect, or Bohr shift.
