1. Which of the following statements best describes the hydrogen bonding network between deoxyhemoglobin (2HHB) and the Fe-Heme ligand?

a)There are no direct hydrogen bonds between the ligand and hemoglobin amino acids, however there are 2 bridged hydrogen bonds that connect the Fe-heme to the protein via atomic oxygen.

b)There are 2 direct hydrogen bonds between the ligand and hemoglobin amino acids.

c)There are no direct hydrogen bonds between the ligand and hemoglobin amino acids, however there are 2 bridged hydrogen bonds that connect the Fe-heme to the protein via a water molecule.

d)There are no hydrogen bonds between the ligand and hemoglobin amino acids.

Which of the following statements best describes how 2,3-bisphosphoglycerate (2,3-BPG) reduces hemoglobin's affinity for oxygen? 2,3-BPG binds to the heme iron and prevents oxygen from binding. 2,3-BPG binds to positively charged Lys and His residues in the center of the hemoglobin, stabilizing the T (low-affinity) state. 2,3-BPG binds to the amino termini and stabilizes the R state. 2,3-BPG binds to the α1β1-α2β2 interface and stabilizes the R state.
