Which of the following best describes the effect of increased temperature on hemoglobin's affinity for oxygen?

A Increased temperature increases hemoglobin's affinity for oxygen
B Increased temperature decreases hemoglobin's affinity for oxygen ✓
C Temperature has no effect on hemoglobin's affinity for oxygen
D The effect of temperature on hemoglobin's affinity for oxygen is variable and depends on pH

Explanation

An increase in temperature leads to a decrease in hemoglobin's affinity for oxygen. This relationship is part of the physiological response that helps deliver more oxygen to tissues during increased metabolic activity or fever.
