Bohr Effect - Effects of Cooperativity

Effects of Cooperativity

The Bohr effect is dependent on cooperative interactions between the hemes of the hemoglobin tetramer. This is evidenced by the fact that myoglobin, a monomer with no cooperativity, does not exhibit the Bohr effect. Hemoglobin mutants with weaker cooperativity may exhibit a reduced Bohr effect.

In the Hiroshima variant hemoglobinopathy, cooperativity in hemoglobin is reduced, and the Bohr effect is diminished. During periods of exercise, the mutant hemoglobin has a higher affinity for oxygen and tissue may suffer minor oxygen starvation.

Famous quotes containing the words effects of and/or effects:

    Some of the greatest and most lasting effects of genuine oratory have gone forth from secluded lecture desks into the hearts of quiet groups of students.
    Woodrow Wilson (1856–1924)

    Trade and commerce, if they were not made of India-rubber, would never manage to bounce over the obstacles which legislators are continually putting in their way; and, if one were to judge these men wholly by the effects of their actions and not partly by their intentions, they would deserve to be classed and punished with those mischievous persons who put obstructions on the railroads.
    Henry David Thoreau (1817–1862)
