The Bohr Effect Is Due in Part to

Multiple Choice

The Bohr effect is due in part to

A) relatively low pKa (i.e. weaker base) for histidyl residues because of their proximity to ionized aspartyl residues in oxyhemoglobin.
B) a relatively high pKa (i.e. stronger base) for histidyl residues because of their proximity to arginyl residues in deoxyhemoglobin.
C) a relatively high pKa for histidyl residues because of their proximity to ionized aspartyl residues in deoxyhemoglobin.
D) a relatively low pKa for histidyl residues because of their proximity to arginyl residues in deoxyhemoglobin.
