Increased temperature results in decreased o2 unloading from hemoglobin.
a. true
b. false

False.

Explanation:

The main function of hemoglobin is to transport oxygen to the various cells of the body. For this process to occur the oxygen from the lungs gets attached to the hemoglobin and travels throughout the body to reach at every possible place.

This hemoglobin also gets attached to the carbon dioxide from various cells of the body to lungs for gaseous exchange.

There are many factors that affect the loading and unloading of oxygen from hemoglobin. The increased temperature increases the rate of unloading of oxygen from hemoglobin and increased temperature does not favors loading of oxygen to hemoglobin.

Hence, the given statement is False.
