The hemoglobin of a human fetus a. is the same as that of an adult. b. has a higher affinity for $\mathrm{O}_{2}$ than adult hemoglobin has. c. has only two protein subunits instead of four. d. is supplied by the mother's red blood cells. e. has a higher affinity for BPG than adult hemoglobin has.
A human fetus produces hemoglobin with a higher affinity for $\mathrm{O}_{2}$ than adult hemoglobin. As fetal blood exchanges materials with the mother's blood in the placenta, in what direction does $\mathrm{O}_{2}$ move? What would happen to a fetus with adult hemoglobin? What would happen if fetal hemoglobin had a lower affinity for $\mathrm{O}_{2}$ than adult hemoglobin?
The hemoglobin of a human fetus $a .$ is the same as that of an adult. $b$. has a higher affinity for $\mathrm{O}_{2}$ than adult hemoglobin has. $c .$ has only two protein subunits instead of four. $d$. is supplied by the mother's red blood cells. $e .$ has a lower affinity for $\mathrm{O}_{2}$ than adult hemoglobin has.
