questions with correct answers
Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R
(relaxed) state - Ans:-True
When hemoglobin changes from the T to the R, it has a high affinity for oxygen - Ans:-True
When h...
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+) - Ans:✔✔-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. -
Ans:✔✔-True
Myoglobin stores oxygen, whereas hemoglobin transports oxygen. Myoglobin has a higher affinity for
oxygen compared to hemoglobin - Ans:✔✔-True
Hemoglobin is an oxygen transport protein, whereas myoglobin is an oxygen storage protein. They
exhibit different binding curves when plotted on a graph with total partial pressure of the oxygen (x-axis)
plotted against the percentage saturation of hemoglobin (y-axis). What pattern of binding curves do
these proteins exhibit? - Ans:✔✔-Hemoglobin has a sigmoidal curve whereas the myoglobin has a
hyperbolic curve.
Hemoglobin and myoglobin proteins bind to molecular oxygen. However, the protein part of the
hemoglobin does not bind directly to the oxygen. Instead a specific atom helps bind the oxygen - -
Ans:✔✔-Iron
The symptoms of sickle cell anemia are primarily because red blood cells are misshaped, due to -
Ans:✔✔-a mutation in the beta hemoglobin gene which leads to the insertion of valine into the
hydrophobic patches on deoxygenated hemoglobin
