Which of the following is true of myoglobin?
A) its Hill coefficient is less than that of hemoglobin
B) it carries the same amount of oxygen as hemoglobin on a molar basis
C) its binding of oxygen represents positive cooperativity
D) its binding of oxygen is affected by 2,3-BPG

Question

Quizplus · Accepted Answer

Myoglobin has a Hill coefficient of 1, indicating that it does not exhibit cooperativity in its binding of oxygen, unlike hemoglobin which has a Hill coefficient greater than 1, indicating positive cooperativity in oxygen binding. Myoglobin's oxygen binding is not affected by 2,3-BPG, and it does not exhibit positive cooperativity. It also carries oxygen more efficiently on a per-molecule basis compared to hemoglobin.
