Which of the following statement is correct about the respiratory pigments?
Correct answer: C. Myoglobin has more affinity for oxygen as compared to haemoglobin
- A. Albumin, globulin and globular proteins are present in respiratory pigments
- B. Myoglobin and haemoglobin has higher affinity for nitrogen
- C. Myoglobin has more affinity for oxygen as compared to haemoglobin
- D. Cyanide and haemoglobin has low affinity for oxygen
Explanation
Myoglobin, a respiratory pigment found in muscle cells, has a higher affinity for oxygen compared to hemoglobin. Myoglobin binds oxygen at lower oxygen partial pressures (like those found in tissues) and releases it at higher oxygen partial pressures (like those in the lungs).
