Which of the following will shift the reaction shown below to the right? HHb + O₂ HbO₂^- + H⁺

Question

Quizplus · Accepted Answer

In this reaction, HHb is converted into HbO₂^-, which releases a proton (H+) to the solution. Therefore, if the pH of the solution is increased, the equilibrium will shift to the right to consume the added H+ ions and produce more HbO₂^-. On the other hand, decreasing the partial pressure of O₂ (analogous to decreasing the concentration of O₂) will cause the equilibrium to shift to the left because the reaction will consume less O₂ to form HbO₂^-. Therefore, the correct answer is A.
