Which of the following curves is representative of the binding of oxygen to myoglobin? 
A) curve A 
B) curve B 
C) curve C 
D) curve D

Quizplus · Accepted Answer

Curve A represents the typical binding curve for myoglobin, which has a high affinity for oxygen, meaning that it can bind oxygen readily at very low partial pressures. This curve is steep at low partial pressures and plateaus at higher partial pressures, indicating that almost all the oxygen is bound to myoglobin at these concentrations. Curves B, C, and D are not representative of myoglobin's binding curve as they either have a lower affinity or exhibit cooperative binding tendencies.
