Is the correct answer choice false in this question? Cooperative Binding

1. The four subunits of hemoglobin exhibit cooperative binding. As pO2 of blood changes entering the pulmonary veins, the KM of hemoglobin towards this substrate:

• (A) Increases
• (B) Decreases
• (C) Remains Unchanged
• (D) Could be higher or lower, depending on the saturation

The answer is C. At first, this makes sense because changing the substrate concentration should not affect KM, however this fails to take into account the "right shift" that occurred at your...
