Question

What is the primary reason gamma subunits in fetal hemoglobin enhance oxygen affinity?

Accepted Answer

Gamma subunits have a lower affinity for BPG compared to beta subunits.

Answer

Gamma subunits bind oxygen more tightly than beta subunits.

Answer

Gamma subunits are more flexible, allowing easier oxygen binding.

Answer

Gamma subunits increase the overall size of hemoglobin, allowing more oxygen to bind.
