Question

Which of the statements below is false about myoglobin and hemoglobin?

a. myoglobin has a greater affinity for oxygen than hemoglobin
b.cooperative binding and All-American regulation of hemoglobin allow oxygen to be unloaded at low partial pressures of oxygen in the tissues
c.a hyperbolic curve of myoglobin differs from a sigmoidal curve of hemoglobin in that the hyperbolic curve binds more oxygen after the initial proteins first bind oxygen
d. the main property of myoglobin and hemoglobin that makes them an efficient system for oxygen delivery from lungs to muscles is the different binding affinities for oxygen

Explanation / Answer

The false statement is (d) the main property of myoglobin and hemoglobin that makes them an efficient system for oxygen delivery from lungs to muscles is the different binding affinities for oxygen.

This is because both myoglobin and hemoglobin have almost have similar binnding affinities.
