Bohr Shift (Right)
Bohr Shift (Right)
A shift in the oxygen-hemoglobin dissociation curve to the right, indicating a decreased ability of hemoglobin to bind oxygen.
Bohr Shift (Left)
Bohr Shift (Left)
A shift in the oxygen-hemoglobin dissociation curve to the left, indicating an increased ability of hemoglobin to bind oxygen.
Bohr Effect
Bohr Effect
The change in the affinity of hemoglobin for oxygen, influenced by factors like temperature, pH, and partial pressures of CO2 and O2.
