Flashcards
Bohr Shift
Bohr Shift
The Bohr shift describes the change in the oxygen-hemoglobin dissociation curve due to factors like temperature, acidity, and partial pressures of CO2 and O2.
Rightward Shift
Rightward Shift
An increase in temperature, acidity, or partial pressure of CO2 shifts the oxygen-hemoglobin dissociation curve to the right. This means hemoglobin releases oxygen more readily.
Leftward Shift
Leftward Shift
A decrease in temperature, acidity, or partial pressure of CO2 shifts the oxygen-hemoglobin dissociation curve to the left. This means hemoglobin holds onto oxygen more tightly.
