WebA paper by Perutz et al. (1980) identified at least two amino acid residues in hemoglobin that account for the Bohr effect by interacting directly with H +. CO 2 is not directly involved. Further, the Bohr effect (and the Root effect) are defined in terms of pH. You and @Cornelius are correct that CO 2 contributes to the Bohr effect but ... 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.
