WebThe Bohr effect (Riggs, 1988) describes the change (Δ) in Hb–O2 affinity that results from a change in H+ concentration and is often expressed numerically as ΔlogP50/ΔpH (Bohr coefficient), where P50 is the PO2 at which 50% of the Hb molecule is saturated, and pH refers to that of the Hb solution. From: Fish Physiology, 1998. WebSep 1, 2024 · For a century, the influence of the Bohr effect on the utilization of blood-borne oxygen has been deemed secondary to its influence on the uptake of carbon dioxide by the blood. Here, we show that the opposite is the case. Using a simple two-ligand, two-state formulation, we modeled the simultaneous oxygen and proton binding to hemoglobin, as ...
