So we decrease our PH, and this causes a decrease in our hemoglobin's ability to bind to oxygen, thereby shifting the entire curve to the right side with respect to the original curve shown in blue. So the blue curve is the oxygen hemoglobin dissociation curve when the PH is 7.4. So when our tissue is not exercising, but if the tissue begins to exercise, that means we produce more H plus ions, and that shifts the entire curve to the right. So the red curve, which describes the PH of, let's say, 7.2, so slightly lower, is shifted to the right side with respect to our blue curve. And this is what we call the Bore Effect. So let's take a look at the following curve at the following diagram and describe exactly how our hemoglobin's ability to oxygen actually decreases.
