BioChem C785 - WGU - Module 3 - all questions 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 1 / 2
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 The Bohr effect is a relationship between hemoglobin's oxygen binding behavior in conjunction with the pH of the surroundings. When the H+ ion concentration increases, the pH of the solution decreases. - CORRECT ANSWER True
