The amount of oxygen released from oxyhemoglobin increases when
A)carbon dioxide concentration decreases.
B)carbon dioxide concentration increases.
C)temperature decreases.
D)blood becomes more alkaline.

Question

Quizplus · Accepted Answer

Bohr effect states that a decrease in pH or increase in CO2 concentration will cause the oxyhemoglobin curve to shift to the right, meaning oxygen is released more easily from the hemoglobin molecule. Therefore, if CO2 concentration increases, more oxygen will be released from oxyhemoglobin. The other options (decrease in CO2 concentration, decrease in temperature, or blood becoming more alkaline) would cause a shift to the left, meaning less oxygen would be released.
