Question

Which of the following is an example of the Bohr effect? the exchange of bicarbonate for Cl-through the erythrocyte plasma membrane the exchange of Cl- for bicarbonate through the erythrocyte plasma membrane an increase in H+ causes the dissociation of O2 from hemoglobin CO2 forms carbamino compounds CO2 reacts with hemoglobin and causes the dissociation of O2 from hemoglobin

Answer 1

The answer is - an increase in H+ causes the dissociation of O2 from hemoglobin

Explanation -

Bohr's effect is the increase in CO2 or the concentration of H+ ions in the blood, causing the dissociation of O2 from the hemoglobin.

when CO2 released in the bloodstream, it reacts with water (H20) and forms bicarbonate and protons through the following reactions:-

${\displaystyle {\ce {CO2 + H2O <=> H2CO3 <=> H+ + HCO3^-}}}$

An increase in the concentration of H+ ions lowers the PH of the blood, which promotes the dissociation of oxygen from Hemoglobin.
