Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the following will lower the affinity of hemoglobin for oxygen? correct answer: Increase in 2,3 bisphosphoglycerate (BPG) A decreased affinity will increase the rate of oxygen delivery to the tissues. This will occur when pH is low, there is an increase in CO2, protons or 2,3 BPG. The other scenarios (a, c, d) will all increase the affinity for O2. Which of the following proteins ...
