Question

The oxygen-binding curve for myoglobin is steep and shifted to the left of the same curve for hemoglobin. This indicates that (A) people with myoglobin are acclimated for life at high altitudes. (B) myoglobin occurs in high concentration in the human foetus. (C) myoglobin does not function well at high percent saturation of oxygen. (D) myoglobin picks up and releases O2 at lower Po2 values than does haemoglobin.

A left shift in the oxygen-binding curve means that the pigment operates at lower PO2 values.

Q. The oxygen-binding curve for myoglobin is steep and shifted to the left of the same curve for hemoglobin. This indicates that

people with myoglobin are acclimated for life at high altitudes.

myoglobin occurs in high concentration in the human foetus.

myoglobin does not function well at high percent saturation of oxygen.

myoglobin picks up and releases O $_{2}$ at lower Po $_{2}$ values than does haemoglobin.

A left shift in the oxygen-binding curve means that the pigment operates at lower PO $_{2}$ values.
