Quizplus · Accepted Answer

Increased carbon dioxide and decreased pH indicate a higher level of acidity within the body, which favors unloading of oxygen from the hemoglobin molecule. This occurs due to the Bohr effect, which states that the affinity of oxygen to hemoglobin decreases when there is an increase in carbon dioxide and a decrease in pH.
