An increase in hemoglobin affinity for oxygen occurs with
A) hyperthermia.
B) shift to the right.
C) elevated PCO₂.
D) shift to the left.

Question

Quizplus · Accepted Answer

An increase in oxygen affinity is known as a shift to the left on the dissociation curve.Hyperthermia does not have an effect on the hemoglobin affinity.Elevation in PCO₂ is seen with changes in pH.A decrease in the oxygen affinity is associated with a shift to the right on the oxyhemoglobin dissociation curve.
