Which of the following statements about the figure is
correct?
A. Protein A is a monomer, while protein B is a tetramer
B. Protein A is myoglobin while protein B is hemoglobin
C. Protein A shows noncooperative binding while protein B
exhibits cooperative binding for oxygen.
D. Protein A has a higher affinity and therefore binds faster
with oxygen while protein B has a lower affinity for binding
to oxygen.
E. Protein A will bind more oxygen and therefore has a
higher saturation than protein B.
