An increase in the plasma PCO₂ and a decrease in PO₂ cause an increase in the dissociation of CO₂ from hemoglobin.

Question

Quizplus · Accepted Answer

An increase in plasma PCO₂ actually leads to an increase in the association of CO₂ with hemoglobin to form carbaminohemoglobin, not a dissociation. The decrease in PO₂ facilitates the release of oxygen (Bohr effect), but it does not directly cause an increase in the dissociation of CO₂ from hemoglobin.
