In one type of hemoglobin mutant the amino acid change generates a strong ionic interaction stabilizing the T state conformation, but only under conditions of lower pH, e.g., at pH 7.2 compared to pH 7.6. Explain what effect this mutation would have on the amount of O2 delivered to the tissue. More O2 delivered to the tissue because the R-T equilibrium would be shifted to the T state in tissues. More O₂ delivered to the tissue because the R-T equilibrium would be shifted to the T state in lungs. Less O2 delivered to the tissue because the R-T equilibrium would be shifted to the T state in lungs. Less O₂ delivered to the tissue because the R-T equilibrium would be shifted to the T state in tissues. More O2 delivered to the tissue because the R-T equilibrium would be shifted to the R state in tissues.
