And that's exactly why, in such a case, when we decrease the temperature we shift the entire curve to the left side with respect to the original blue curve. So in this diagram, the blue curve is our normal temperature curve, but the red curve is the lower temperature. And so we shifted entirely to the left side and at a pressure of 40 mercury inside our tissue. At a lower temperature, the cells will carry out metabolic processes at a lower rate. They will therefore require less oxygen. And so hemoglobin will be less likely to actually unload that oxygen.
