Question 1

Which of the following statements about the binding of oxygen to deoxyhemoglobin is correct?

Accepted Answer

A) The binding of oxygen to Fe2+ in the first heme pulls the iron ion into the porphyrin ring, decreasing the affinity for the second oxygen. 
B) The binding of oxygen to Fe2+ in the first heme pushes the iron ion out of the porphyrin ring, decreasing the affinity for the second oxygen. 
C) The binding of oxygen to Fe2+ in the first heme pulls the iron ion into the porphyrin ring, increasing the affinity for the second oxygen. 
D) The binding of oxygen to Fe2+ in the first heme pushes the iron ion out of the porphyrin ring, increasing the affinity for the second oxygen. 
E) Oxygen does not bind to deoxyhemoglobin.
