Bohr's curve
WebMar 27, 2024 · The oxyhemoglobin dissociation curve is a vital tool for comprehending how blood transports and releases oxygen. Oxygen is carried throughout the body primarily by a protein molecule, hemoglobin, which is present inside red blood cells. Oxygen can also be carried throughout the body by dissolving in blood plasma, but this dissolved portion only ... Web27. The Bohr effect is a relationship between hemoglobin's oxygen binding behavior in conjunction with the pH of the surroundings. When the H+ ion concentration increases, the pH of the solution _________________. decreases. when pH decreases H+ concentration increases, and vice versa. Oxygen concentration has no direct effect on pH.

The Bohr effect is a phenomenon first described in 1904 by the Danish physiologist Christian Bohr. Hemoglobin's oxygen binding affinity (see oxygen–haemoglobin dissociation curve) is inversely related both to acidity and to the concentration of carbon dioxide.
