Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R (relaxed) state Correct Answer-True When hemoglobin changes from the T to the R, it has a high ... affinity for oxygen Correct Answer-True When hemoglobin changes from the R to T, it has a low affinity for oxygen Correct Answer-True Cooperatively refers to Correct Answer-structural changes that increases the affinity for oxygen in hemoglobin When the oxygen concentration is high, the heme shape is planar. When the oxygen concentration is low, the heme shape is bent shape. Correct Answer-True The Bohr effect is a relationship between hemoglobin's oxygen binding behavior in conjunction with the pH of the surroundings. When the pH is low, hemoglobin has low affinity for oxygen and releases oxygen Correct Answer-True Bohr effect is a relationship between hemoglobin's oxygen binding behavior in conjunction with the pH of the surroundings. When the pH is high, hemoglobin has high affinity for oxygen and binds oxygen. Correct Answer-True Relative to the lungs, the pH in the peripheral tissues is lower, because the CO2 generated by metabolism is converted to bicarbonate, which releases proton (H+) Correct Answer-True [Show More]
