Community Answer
Read the following about blood pigments :i. Hemoglobin is the pigment ...
Explanation:

Hemoglobin:
- Hemoglobin is the pigment present in our blood and is an iron-containing protein.
- It is a vital component of red blood cells (RBCs) and is responsible for carrying oxygen from the lungs to the rest of the body.
- Hemoglobin consists of four protein subunits, each containing a heme group. The heme group contains an iron ion that can bind to oxygen.
- This ability to bind and release oxygen allows hemoglobin to transport oxygen efficiently throughout the body.

Haemocyanin:
- Haemocyanin is the pigment present in the blood of Palaemon, a type of crustacean, and is a copper-containing protein.
- Unlike hemoglobin, which is found in vertebrates, haemocyanin is found in some invertebrates like mollusks and arthropods.
- Haemocyanin is involved in carrying oxygen in these organisms, but it has a different structure and mechanism compared to hemoglobin.
- Haemocyanin contains copper ions instead of iron ions and has a bluish color when oxygenated, giving some animals a blue blood color.

Efficiency:
- The statement that haemocyanin is much more efficient than hemoglobin is incorrect.
- Hemoglobin is highly efficient in transporting oxygen, and its structure and mechanism are well-suited for this purpose.
- Haemocyanin, on the other hand, has a lower oxygen-carrying capacity compared to hemoglobin.
- Hemoglobin has a higher affinity for oxygen, allowing it to bind and release oxygen more readily, which is essential for efficient oxygen transport.
- Haemocyanin, due to its copper ions, has a lower affinity for oxygen and a slower oxygen-binding kinetics.
- Therefore, hemoglobin is considered more efficient in oxygen transport compared to haemocyanin.

Conclusion:
- Based on the above explanations, only statements i) and ii) are correct, and statement iii) is incorrect.
- Therefore, the correct answer is option 'D': only statement i) and ii) are correct.
