WebThe Root effect refers to a decrease in the affinity and O2carrying capacity of hemoglobin when pH decreases or when PCO2 increases. As a result, if oxygen-rich blood is exposed to low pH or high CO2 levels, it will release more oxygen than if the Root effect was absent. The physoclyst swim bladder is filled mostly with oxygen. WebBohr effect noun ˈbȯr- : the decrease in the oxygen affinity of a respiratory pigment (such as hemoglobin) in response to decreased blood pH resulting from increased carbon dioxide concentration in the blood Word History Etymology Christian Bohr †1911 Danish physiologist First Known Use 1922, in the meaning defined above Time Traveler
