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

ANSWERS: True

When hemoglobin changes from the T to the R, it has a high affinity for oxygen

ANSWERS: True

When hemoglobin changes from the R to T, it has a low affinity for oxygen

ANSWERS: True

Cooperatively refers to

ANSWERS: 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.

ANSWERS: 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

ANSWERS: 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.

ANSWERS: 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+)ANSWERS: 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.

ANSWERS: True

Myoglobin stores oxygen, whereas hemoglobin transports oxygen. Myoglobin has a higher affinity for
oxygen compared to hemoglobin

ANSWERS: True
