Describe the bohr effect
WebBohr Effect. The 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. ... Describe the Bohr effect ... WebNov 13, 2024 · Various factors can affect the affinity of haemoglobin for oxygen: pH/pCO2 – When H + /pCO 2 increases and pH decreases, Hb enters the T state and its affinity for oxygen decreases. This is known as the Bohr effect. Inversely, when H + /pCO 2 decreases and pH increases, the affinity of haemoglobin for oxygen increases.
