Bohr's curve

WebIn terms of pH change (the Bohr Effect), the curve of the lower pH shifts to the right while the curve of the higher pH shifts to the left. However, the starting point for both of the sigmoidal-shaped curves is at PO 2 of 9.1mmHg, where 6.9259% saturation is for pH 6.8 and 8.3333% saturation is for pH 7.4. Discussion WebWe find the Bohr model of H 2 admits other solutions than the symmetric one he considered (pictured in Fig. 1). These solu-tions provide a fairly good description of the ground-stateE(R) (see curve 2 in Fig. 3) at large as well as small internuclear spacing R, in contrast with the result of Bohr (see curve 1 in Fig. 3).

WebJun 1, 2007 · Oxygen dissociation curves (ODCs) for human hemoglobin (Hb) at 3 different pH levels. The “S” shape of the curves is due to the fact that Hb begins to absorb O 2 rapidly when O 2 levels are between 20 and 40 mmHg. The Bohr effect is illustrated here by the shift of the curve to the right as pH decreases. WebThe Bohr effect describes hemoglobin’s lower affinity for oxygen secondary to increases in the partial pressure of carbon dioxide and/or decreased blood pH.
