27. Which of the following would increase Oz unloading in the tissues
a. an increase in altitude
b. a decrease in temperature
a a decrease in pH in the tissue
d. an increase in PO2 in the tissue
e a decrease in BPG (bis-phospho-glycerate)

C

Explanation:

A decrease in the tissue's pH means that there's a lot of carbon dioxide. To get rid of the carbon dioxide, the oxyheamoglobin will have to release its oxygen and gain the protons produced from the dissociation of carbonic acid (produced by the reaction between water and carbon dioxide in the presence of carbonic anhydrase). Carbon dioxide will then be carried in the blood as bicarbonate ion.
