Like typical fish, the crocodile icefish still need and use oxygen for metabolism. Explain why only fish that evolved to live in cold waters, like the crocodile icefish, could lose hemoglobin? ( unlike terrestrial organisms, marine organisms like fish use oxygen dissolved in water.)
What do you think happens if you block oxygen from coming into the body and prevent carbon dioxide from leaving in the tracheal system of an insect?
Which statement describes hemoglobin's cooperativity?
A.
When tetrameric hemoglobin binds one molecule of O2, its shape changes to make it bind more readily to a second molecule of O2.
B.
When tetrameric hemoglobin binds one molecule of O2 its shape changes, which prevents binding of any more O2 molecules.
C.
When oxygen is present in the blood, the shape of hemoglobin changes to allow oxygen to bind to it.
D.
When the oxygen concentration in blood decreases, then hemoglobin changes its shape to retain oxygen more readily.
E.
None of the above answer choices correctly describes cooperativity.
