Which of the following has no effect on oxyhemoglobin dissociation?
A) Epinephrine
B) Fever
C) Thyroid hormone
D) Low pH
E) Erythrocyte count

Question

Quizplus · Accepted Answer

Erythrocyte count does not directly affect oxyhemoglobin dissociation. The other options all have an effect on the affinity of hemoglobin for oxygen and therefore impact oxyhemoglobin dissociation. Epinephrine and thyroid hormone increase the affinity of hemoglobin for oxygen, while fever and low pH decrease the affinity.
