Which of the following best describes the effect of increased temperature on the oxygen-binding affinity of hemoglobin?

A Increased affinity for oxygen
B Decreased affinity for oxygen ✓
C No effect on oxygen binding
D Increased release of oxygen to tissues

Explanation

An increase in temperature leads to a decrease in the affinity of hemoglobin for oxygen. This is because higher temperatures increase the kinetic energy of molecules, making it easier for oxygen to be released from hemoglobin.
