a. it binds at adistance from the heme groups of hemoglobin
b. it is normallyfound associated with the hemoglobin molecules that are extractedfrom red blood cells

d. it forms saltbridges with beta chain residues of hemoglobin
e. it binds withhigher affinity to fetal hemoglobin than to adult hemoglobin
Explanation / Answer
e.) It binds with higheraffinity to fetal hemoglobin than to adult hemoglobin. This is the incorrectstatement concerning 2,3-bis phosphoglycerate because fetalhemoglobin exhibits lowaffinity to 2,3-bisphosphoglycerate and results inhigher binding affinity for oxygen.Related Questions
