When We Have A Higher Concentration of CO2. That Means We're Going To Produce a Higher concentration of H plus ions. So one mechanism by which CO2 shifts the curve to the right side is actually by increasing the h plus concentration and therefore decreasing the PH and causing the PH effect. And for the reason we spoke just a moment ago. By increasing the H plus concentration and decreasing the PH, we formed these solve bridges, which stabilize the structure of the T state of the deoxy hemoglobin. That decreases the affinity of hemoglobin for oxygen, shifts the curve to the right side, and allows the hemoglobin to release more o, two molecules to the exercising tissues of our body.
