WGU us TEST NAME: JEO1 27 Fetal hemoglobin differs from adult hemoglobin in that it is able to bind oxygen with greater affinity, allowing the fetus to obtain oxygen from the mother's bloodstream. This greater affinity is due to a single amino acid difference What accounts for this increase in affinity? The different amino acid favors the R state of the protein due to fewer positive charges on the protein subunit The different amino acid causes the deoxygenated hemoglobin to aggregate together. The different amino acid favors the binding of Fest to the heme groups over Fe2+ The different amino acid causes the protein subunits to dissociate and prevents cooperative binding NEXT > BOOKMARKED CLEAR Question navigation 19 20 21 22 23 24 25 26 28 29 30 31 32 33 34 35 36 > NEXT 100% 67/67 A FONT TAKE A BREAK COMMENTS
