Exercising muscle will receive more oxygen from hemoglobin than will relaxed muscle, because: A)its PO₂ is low B)its PCO₂ is high C)both A and B D)both A and B, and its temperature is higher than usual

Question

Quizplus · Accepted Answer

Exercising muscle receives more oxygen from hemoglobin than relaxed muscle due to a combination of factors: a lower pH (indicating an increase in acidity), a higher partial pressure of carbon dioxide (PCO2), and an increase in temperature. These conditions all promote the release of oxygen from hemoglobin, a phenomenon described by the Bohr effect.
