An unstable type of hemoglobin that cannot bind with oxygen is termed:
a. deoxyhemoglobin.
b. oxyhemoglobin.
c. methemoglobin.
d. glycosylated hemoglobin.
ANS: C
Without reactivation, the Fe3+-containing hemoglobin (methemoglobin) cannot bind with oxygen. Deoxyhemoglobin is reactivated hemoglobin whose oxygen has been released. Binding of oxy-gen to ferrous iron temporally oxidizes Fe2+ to Fe3+ as in oxyhemoglobin. Glycosylated hemoglo-bin is glucose bound to hemoglobin.
