WebSo the first one, talking about carbon dioxide and protons, their effect is called the Bohr effect. So you might see that word or this description. This is the Bohr effect. And the other one, looking at it from the other prospective, looking at it from oxygen's perspective, this would be the Haldane effect. WebJun 8, 2015 · The x° and y° coordinates represent the point of symmetry of the curve. x° is particularly interesting - it is the magnitude of the left and right shift, determined by the Bohr effects (i.e. the pH, pCO 2, dyshemoglobin levels and the concentration of 2,3-DPG) as well as the temperature.
